In principle, HIPEs are generated by mixing of two immiscible liquids with more than 74 % of internal phase in the presence of an adequate surfactant. Upon polymerization of the monomers in the external phase, polyHIPE with highly porous and rigid structure is formed. Accordingly, different classes of materials, ranging from co-polymers, interpenetrating polymer networks (IPN), or semi-IPN to inorganic decorated structures can be generated. It is worth noting that it is possible to transform on purpose such materials into porous and conductive carbon foams by pyrolysis. Moreover, as powerful improvement pathways in terms of selectivity and sensitivity, several approaches and procedures for immobilizing task-specific recognition functions as thin layer onto the surface of polyHIPE based materials have been used. This set of polyHIPE derived materials have been applied to a wide spectrum of applications, such as, separation and gas storage, catalysis and biomedical application among others. Via this review, our utmost aim is to highlight recent advancements in the understanding of different aspects of polyHIPE as promising sensing platforms for development of electrochemical sensors and biosensors.</div></div>","PeriodicalId":315,"journal":{"name":"European Polymer Journal","volume":"226 ","pages":"Article 113747"},"PeriodicalIF":5.8,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143128362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maintaining ADR at 1.2 wt%, the increase in PBS content significantly enhances the crystallinity and Young’s modulus of PBAT increasing from 8.4 % to 25.3 % and from 46.6 MPa to 186.7 MPa, respectively.

Nonetheless, there is no proof that the cutin monomer, i.e. 10,16-dihydroxy hexadecanoic acid (10,16-diHHDA) largely found in tomato peel, can be used as a curing agent, due to a lack of sufficiently pure samples of this fatty acid. In this work, the cutin monomer was firstly successfully isolated by up-cycling tomato-dried peels with a purity averaging 92 % and a 67 % recovery rate. 10,16-diHHDA was then used as a trifunctional reactive component to develop fully bio-based epoxy coatings formulated with three different epoxidized precursors. Using a phloroglucinol epoxidized precursor, an increase in the ratio between epoxy groups and hydrogen-active nucleophiles increased the glass transition temperature, up to an average of 104 °C, along with enhanced hardness and adhesion to steel and aluminum alloy surfaces. Additionally, all the cutin-derived coatings exhibited higher hydrophobicity than a reference bisphenol-A-containing coating. The most promising bio-based resin formulations were finally used to coat carbon steel samples and the protection ability against corrosion in a 3.5 wt% NaCl solution was assessed through a multi-step electrochemical testing protocol to investigate continuum phenomena at both medium|coating and coating|metal interfaces. As a result, two resin compositions (namely PC_4:1_5 and PC_5:1_3, differing for the amounts of the cutin monomer and catalyst) were identified as the most protective coatings in terms of both instant and long-term performance.
