Growing plastic production, population, and consumption are driving increased environmental pollution and waste. Without change, 12 billion metric tons of plastic waste could fill landfills or natural environments by 2050. Moving beyond the fossil fuel era towards sustainability demands using advanced renewable materials that emit minimal, or net-zero carbon emissions. Cellulose, the most abundant biopolymer found in nature, is a compelling foundation for designing functional materials. This review paper fills the void regarding the esterification of cellulose to obtain specific organic cellulose esters (CEs), its modification by incorporating agents for improved processability, and blending with biopolymers as a powerful method for obtaining materials with enhanced property-to-cost performance. Further investigation is necessary to delve into the correlations among miscibility, structure, and properties of these materials to fully exploit the potential of this approach. The miscibility of CEs with other biopolymers can vary, with partial or complete miscibility attributed to the chemical nature of polymers, hydrophilic and hydrophobic properties. This variation is a key reason for studying current compatibilization strategies. This article aims to examine the advancements in strategies for compatibilizing CE blends with biodegradable polymers, along with exploring the biodegradation behavior and applications of both unmodified and modified blends.

Most plastics in use today are derived from petrochemical resources, resulting in severe environmental problems. As fossil resources are depleting, polymers derived from sustainable feedstock and manufacturing routes have become increasingly in demand. However, producing bio-based polymeric materials with desired properties remains challenging. Recently, 1,2-dithiolane-containing molecules, such as biogenic thioctic acid, have gained substantial attention as promising feedstocks for developing polymers with advanced features. These molecules can be widely found in animals and plants, and feature a unique five-membered disulfide ring that endows the derived polymers with a combination of functions and properties that rarely appear in traditional biogenic polymers or classical supramolecular polymers. These include responsiveness, biocompatibility, biomedical function, self-healing capability, adhesiveness, recyclability, degradability and tuneable mechanical properties spanning from soft to stiff, without requiring elaborate synthetic processes. In this review, we provide a comprehensive review of the recent advancement in 1,2-dithiolane-containing polymers, summarising their preparation strategies, comparing the latest advances in their properties and discussing their corresponding applications. Finally, we discuss the challenges that need to be addressed in order to integrate these materials harmonically into our daily lives. This review is expected to promote the exploration in the functionalities and applications of sustainable dynamic covalent biomass-based polymers.

Membranes with advanced and novel functions play important roles in emerging applications ranging from industrial separations, water purification, energy harvesting and storage, healthcare, biomimetic membranes and more. The performance of membranes in these critical applications is fundamentally determined by their interfacial interactions with surrounding ions, molecules, particles, emulsions, and bioactive agents. Amphiphilic copolymers containing both hydrophobic and hydrophilic segments will spontaneously assemble into multiphase and hierarchical structures, providing a general solution for regulating the surface physicochemical properties of membranes used in the aforementioned urgent applications. Controlled synthesis of amphiphilic copolymers and the methods for fabricating membranes from these copolymers with predetermined performance are fundamentally important for their applications. In this work, we first summarize the polymerization techniques for synthesizing amphiphilic copolymers used for membrane materials. We then review the methods for fabricating membranes from amphiphilic copolymers and highlight the urgent applications of advanced functional membranes derived from them. We also discuss some remaining challenges and provide insights into future directions, especially as the circular polymer economy and artificial intelligence are setting new requirements for polymer science. This work offers a comprehensive overview of recent advances in functional materials based on amphiphilic polymers, including the working principles and relationships between polymer structure, processing strategies, and membrane performance, which provides new insights into the development of high-performance and next-generation polymeric membranes through the precise, functionality-driven synthesis of novel amphiphilic copolymers and the controlled fabrication of membranes.

The ball-mill grinding (BMG) of polymers has a long history, starting with Staudinger showing in the 1930s that polystyrene undergoes chain scission upon ball milling. However, BMG has significantly expanded from being used solely for polymer degradation to a synthetic tool for a range of applications only in the last decade. Now, BMG has emerged as a promising mechanochemistry technique for several critically important polymer technologies, such as recycling and upcycling, and often provides novel or enhanced mechanochemical reactivity. As a solid-state technique in which solvents are often minimized or eliminated, BMG provides a greener and more sustainable route to various applications. Also, in contrast to many other mechanochemistry techniques that are commonly employed with polymers, BMG has the potential to be scaled to industrially relevant levels. In our review, we provide an extended and deep overview of the phenomena that occur when polymers are subjected to BMG and show how these phenomena can be exploited for various applications. We treat particularly technologies that, especially in the context of our current plastic pollution crisis, are relevant to trending topics in the field of polymer science, such as polymer degradation, chemical recycling, recycling, and upcycling. Other important topics covered in this review include the mechanical activation of responsive polymers, by the use of mechanophores or by exploiting the reactivity of the reactive intermediates generated during chain scission, and polymer-assisted grinding, where polymers serve as additives or reagents to aid in mechanochemical syntheses or other processes.

Stretchable organic photovoltaics have recently garnered significant attention as promising power sources for wearable electronic systems. Especially, research on intrinsically stretchable organic photovoltaics (IS-OPVs) has been accelerated, as the unique advantage of IS-OPVs is their inherent deformability, which does not depend on fabrication processes or pre-treatment methods. Remarkably, the photoactive area increases during stretching, indicating a potential increase in power output and underscoring IS-OPV's strengths as a power source in self-powered electronic systems. Despite rapid advancements in power conversion efficiency and stretchability, IS-OPVs still encounter challenges in market adoption. The most critical performance factor for IS-OPVs is stability, which ensures stable operation under mechanical stress. This review analyses the structural factors that degrade the stability of IS-OPVs. Given their multilayer structure, mechanical failure can result from various complex causes, thus complicating the investigation and comprehensive understanding of the factors that promote performance degradation. This review introduces and discusses recently developed engineering strategies aimed at improving the mechanical stability of IS-OPVs. Furthermore, this review summarizes various experimental methods to assess the performance of IS-OPVs and discusses the insights gained from these experiments in relation to fabricating mechanically stable IS-OPVs with enhanced performance.

Hydrogen bonds (H-bonds) exhibit excellent reversibility, high orientation, and flexible designability among all dynamic non-covalent bonds (DNBs). Herein, the effect of multiple network topologies (including single/double/triple cross-linked networks) in H-bond based dynamic polymeric materials (DPMs) is summarized with the structural design strategies and molecular mechanisms. Additionally, their potential applications in improving mechanical properties, self-healing capabilities, and biomedical fields are also presented in this paper. The first part introduces the basic design principle of single physically cross-linked networks formed by H-bonds. Influenced by the low mechanical strength of H-bonds, the tunability and designability of single H-bonded networks are limited. The second part focuses on the double cross-linked networks via H-bonds and other dynamic interactions, the strategy of exploiting the synergistic enhancement of double networks can improve the comprehensive performance of materials considerably.

Herein, the effect of multiple network topologies (including single/double/triple cross-linked networks) in H-bond based dynamic polymeric materials (DPMs) is summarized with the structural design strategies and molecular mechanisms. Additionally, their potential applications in improving mechanical properties, self-healing capabilities, and biomedical fields are also presented in this paper. The first part introduces the basic design principle of single physically cross-linked networks formed by H-bonds. Influenced by the low mechanical strength of H-bonds, the tunability and designability of single H-bonded networks are limited. The second part focuses on the double cross-linked networks via H-bonds and other dynamic interactions, the strategy of exploiting the synergistic enhancement of double networks can improve the comprehensive performance of materials considerably. Then, the third and fourth parts briefly introduce the research progress of triple cross-linked networks and the biomedical applications of H-bond based DPMs. Finally, the development trend of H-bond based DPMs is predicted based on the above groundbreaking and representative research results.</div></div>","PeriodicalId":413,"journal":{"name":"Progress in Polymer Science","volume":"158 ","pages":"Article 101890"},"PeriodicalIF":26.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142418100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
