Abstract This review highlights the effectiveness and robust nature of eco-friendly room-temperature polymerization initiated in emulsions, and some of its applications in polymer and materials science. The polymerization in emulsions initiated through a thermal or redox approach can be safely conducted under ambient conditions without using other hazardous chemicals. Thermal initiators decompose efficiently at the surfactant-stabilized oil–water interfaces at room temperature. The interface-induced initiation is found to be somewhat independent of surfactant type, insensitive to oxygen, and works for several thermal initiators. Redox initiators without transition metal compounds also effectively initiate room-temperature polymerization in emulsions. With the assistance of room temperature initiation, the polymers synthesized at room temperature are of high molecular mass. In addition, room-temperature polymerization allows temperature-sensitive molecules, for example, proteins and enzymes, to be incorporated with the polymers in situ. The applications of room-temperature polymerization in high internal phase emulsions and biomedicine are also discussed. The initiation of radicals from oil–water interfaces or transition metal-free redox systems is a promising eco-friendly method to promote radical reactions at room temperature. Graphic Abstract

Abstract Elastomeric materials are often used as components that undergo cyclic loading during application, such as tires, seals, and hoses. For this reason, the long-term performance, or more precisely the crack growth behavior, is of great importance. Even though several studies investigated the fatigue behavior of rubber materials during the last 80 years, this topic is still widely under discussion and remains of great interest among scientists. Mars and Fatemi reviewed the developments of the field in the beginning of 2000, however, this paper considers the overall development including new findings to serve as a guide for further investigations in the field of fatigue of elastomers. For this purpose, the usual measurement methods and their evaluation, as well as the most important factors influencing the fatigue behavior, like the formulation of the rubber compound or the application and testing conditions, are explained in detail. Furthermore, an outlook is given on parameters that still need to be scientifically investigated, such as the influence of filler orientations or the selected manufacturing method, in order to fully understand fatigue crack growth.

Abstract Bacterial cellulose (BC) is a natural biopolymer metabolized by Gram-negative bacteria strains in carbon- and nitrogen-rich media. Due to its natural purity, biodegradability, biocompatibility and outstanding mechanical properties, it is considered to be an exceptional biomaterial with versatile scientific and commercial applications. The current review presents data concerning the assembly, structural properties and mechanical behavior of specific biosystems based on bacteria-produced cellulose and polysaccharides derived from plant cell walls. Bacterial cellulose, hemicellulose, their binary composites and ternary composites with pectin are described with respect to the mechanical properties of the obtained materials. The properties of one-component and composite films are discussed with respect to the type of polysaccharides used, their origin and applied pretreatments, as well as various methodological approaches to bacterial cellulose synthesis. This work is focused entirely on the relationship between production methods and composition, and the resulting properties of the obtained materials, it constitutes a universal source of knowledge for specialists from various fields of science and industry.

Abstract With the increasing interest in monitoring health and rapid growth in technology of electronic devices, personal wearable electronics have attracted extensive attention in the recent years. By integrating wearable electronic devices into clothing, accessories, electronic skin products, real-time monitoring and diagnosis of human movement and physiological conditions can be realized. In particular, electrospun micro/nanofibers (MNFs) have the benefits of good breathability, low cost and light weight, owing to their high specific surface area and flexible characteristics making them convenient for wearable devices. In this review, we summarized the existing technologies for synthesizing electrospun MNFs, and classified the materials for preparing wearable physical sensors. Besides the performance and functions of MNFs-based physical sensors; the structure, arrangement and post-treatment of electrospun MNFs have also been described in detail. The operating mechanisms of MNFs-based physical sensors mainly including piezoresistive, piezoelectric, capacitive, triboelectric, thermal-resistive and pyroelectric sensors were briefly discussed, and the typical wearable physical sensory applications based on electrospun MNFs were demonstrated as well.

Abstract Poly(glycerol sebacate) (PGS) and its derivatives have been developed and used for various biomedical applications over the past two decades. Several publications have reviewed the development of PGS from different perspectives, typically focusing on the biofabrication techniques and intended biomedical applications of PGS. However, a comprehensive review of the progress in the research on PGS and its derivatives over the past two decades, in terms of material design, synthesis, and properties have not been conducted. Herein, we review the design and preparation of PGS using different synthesis processes, ranging from the traditional heat curing method to various novel synthesis approaches, before systematically exploring the development of novel PGS derivatives prepared by functional groups modification or (and) hybridizing with other substances. Moreover, a statistical analysis of related publications is presented to quantify the progress in the research on PGS and its derivatives from different perspectives and identify any trends. We expect that this review and the design principles of PGS-based materials summarized herein will inform and promote the further development and optimization of PGS and its derivatives for biomedical applications.

Abstract The diverse structures and unique properties of hydrogels have attracted significant attentions in recent years. Compared to chemically cross-linked hydrogels, natural polymer-based hydrogels cross-linked with physical interactions are environmentally friendly owning to the free of chemical cross-linking agents and exhibit many advantages as diverse reversible non-covalent bonds. This review aims to summarize instructive strategies for designing physical hydrogels based on non-covalent bonds derived from unique functional groups of natural polymers to develop various unique properties and extend the application of corresponding hydrogels. Firstly, strategies to construct the natural polymer-based physically crosslinked hydrogels (NPPCHs) with internal and external stimulating cross-linking characteristics will be introduced. Internal effects included hydrogen bonding, ionic cross-linking, electrostatic interaction, hydrophobic association, and host-guest interaction, and external causes can be temperature, light, pH, or other conditions. Secondly, the unique advantages of processing technologies of NPPCHs including injection, 3D printing, spraying, and molding will be summarized. Thirdly, excellent performances of NPPCHs derived from unique dynamic non-covalent bond structures, such as self-healing, conductivity-promoting, and stimulus-response will be introduced. This review provides guidance to develop the NPPCHs with fascinating structures, excellent properties, and outstanding performances, which will play an important role in promoting the development of physically cross-linked hydrogels.

Abstract Nanofibers have attracted significant interest due to their unique properties such as high specific surface area, high aspect ratio, and spatial interconnectivity. Nanofibers can exhibit multifunctional properties and unique opportunities for promising applications in a wide variety of fields. Hierarchical design strategies are being used to prescribe the internal structure of nanofibers, such as core-sheath, concentric layers, particles distributed randomly or on a lattice, and co-continuous network phases. This review presents a comprehensive overview of design strategies being used to produce the next generation of nanofiber systems. It includes a description of nanofiber processing methods and their effects on the nano- and microstructure. Physico-chemical effects, such as self-assembly and phase separation, on the ultimate morphology of fibers made from designed emulsions, polymer blends, and block copolymers, are then described. This review concludes with perspectives on existing challenges and future directions for hierarchical design strategies to produce internally structured nanofibers.

Abstract Research on polymer-based dielectric materials with low energy loss and high power density for dielectric capacitors can promote the development of advanced energy storage devices and effectively solve energy storage problems. In recent years, all-organic polymer dielectrics have received extensive attention due to the excellent properties and have shown broad development prospects in the energy storage industry. Compared to polymer inorganic composites with bad processability, all-organic dielectrics have proven to be a more suitable option for low-cost and large-scale production. This review summarizes the phased achievements of traditional all-organic polymer dielectrics and the recent progress in polymer modification technology. Meanwhile, the energy storage theory of dielectrics, such as energy storage parameters, polarization mechanisms, breakdown mechanisms, and conduction mechanisms, is thoroughly reviewed. Finally, this paper identifies the existing problems of all-organic polymer dielectric materials and proposes feasible solutions and possible future research priorities.

Abstract This review highlights the ongoing developments on the ring-opening polymerization (ROP) of lactide (LA) and caprolactone (CL) using mononuclear and dinuclear β-diketiminate- and β-ketoiminate-substituted metal complexes. The resulting aliphatic polyesters are of great interest as sustainable replacements to petrochemicals-based polymers with potential applications in tissue engineering, bio-medical, and agricultural sciences. β-Diketiminate and β-ketoiminate metal complexes are very promising ROP catalysts since their steric and electronic properties, and hence their catalytic activity and selectivity can be easily modified. This review compares different classes of β-diketiminate and β-ketoiminate complexes with respect to the controlled synthesis of homopolymers and copolymers of aliphatic polyesters and elaborates on the polymerization kinetics and mechanistic studies.

Abstract The need for achieving sustainable technologies has encouraged research on renewable and biodegradable materials for novel products that are clean, green, and environmentally friendly. Nanocellulose (NC) has many attractive properties such as high mechanical strength and flexibility, large specific surface area, in addition to possessing good wet stability and resistance to tough chemical environments. NC has also been shown to easily integrate with other materials to form composites. By combining it with conductive and electroactive materials, many of the advantageous properties of NC can be transferred to the resulting composites. Conductive polymers, in particular poly(3,4-ethylenedioxythiophene:poly(styrene sulfonate) (PEDOT:PSS), have been successfully combined with cellulose derivatives where suspensions of NC particles and colloids of PEDOT:PSS are made to interact at a molecular level. Alternatively, different polymerization techniques have been used to coat the cellulose fibrils. When processed in liquid form, the resulting mixture can be used as a conductive ink. This review outlines the preparation of NC/PEDOT:PSS composites and their fabrication in the form of electronic nanopapers, filaments, and conductive aerogels. We also discuss the molecular interaction between NC and PEDOT:PSS and the factors that affect the bonding properties. Finally, we address their potential applications in energy storage and harvesting, sensors, actuators, and bioelectronics.

Nanocellulose (NC) has many attractive properties such as high mechanical strength and flexibility, large specific surface area, in addition to possessing good wet stability and resistance to tough chemical environments. NC has also been shown to easily integrate with other materials to form composites. By combining it with conductive and electroactive materials, many of the advantageous properties of NC can be transferred to the resulting composites. Conductive polymers, in particular poly(3,4-ethylenedioxythiophene:poly(styrene sulfonate) (PEDOT:PSS), have been successfully combined with cellulose derivatives where suspensions of NC particles and colloids of PEDOT:PSS are made to interact at a molecular level. Alternatively, different polymerization techniques have been used to coat the cellulose fibrils. When processed in liquid form, the resulting mixture can be used as a conductive ink. This review outlines the preparation of NC/PEDOT:PSS composites and their fabrication in the form of electronic nanopapers, filaments, and conductive aerogels. We also discuss the molecular interaction between NC and PEDOT:PSS and the factors that affect the bonding properties. Finally, we address their potential applications in energy storage and harvesting, sensors, actuators, and bioelectronics.","PeriodicalId":20326,"journal":{"name":"Polymer Reviews","volume":"19 1","pages":"437 - 477"},"PeriodicalIF":13.1,"publicationDate":"2022-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81266957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
