The use of amphiphilic polymers as stabilizers in emulsion polymerization and miniemulsion polymerization (hereafter collectively referred to as “(mini)emulsion polymerization” presents a highly tunable option to help mitigate the associated drawbacks of small-molecule surfactants. Although the stabilizer is used in relatively small amounts (typically ∼3 wt% of the total polymer), it has large impacts on (mini)emulsion polymerization from a mechanistic perspective as well as on final product properties. This review outlines considerations that need to be taken into account when using polymeric stabilizers in (mini)emulsion polymerization. For the convenience of the reader, this review starts with some background on (mini)emulsion polymerization and colloidal stabilization. Next, the mechanistic aspects to consider when using polymeric stabilizers in emulsion polymerization are outlined, with a large focus on the complexity of the nucleation stage. This discussion is then extended to miniemulsion polymerization. As stabilizers are present on the particle surface post-polymerization, the impact on rheological properties and film formation is then discussed, followed by various applications of polymer particles enabled using polymer particles. Special focus is drawn to how the stabilizer itself can be used to tailor the surface of particles for various applications. Finally, we conclude with a summary and an outlook on the state of polymeric stabilizers in (mini)emulsion polymerization.</div></div>","PeriodicalId":413,"journal":{"name":"Progress in Polymer Science","volume":"175 ","pages":"Article 102090"},"PeriodicalIF":26.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146033791","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}

Water electrolysis operates under diverse conditions—including high temperature, high pressure, and strongly acidic or alkaline environments—depending on the electrolyzer type. Ensuring long-term membrane durability under such conditions is critical.

Furthermore, we discuss the critical need for methods to quantify optical transparency for bulk thick plastic glass materials beyond the current state-of-the-art thin film refractive index measurements, which often do not translate to optical properties in thick bulk glass.

Reported values for optical absorption coefficients using reproducible protocols remain difficult to find in the modern literature, even for established commodity plastic optics. Hence, we review the methods to determine optical absorption coefficients and properly correct for Fresnel reflection in transmission measurements to enable accurate comparison of different optical materials.

Lignocellulosic biomass, primarily composed of lignin and carbohydrates, holds great promise as a renewable feedstock for the production of bio-based chemicals, fuels, and materials, thereby reducing our reliance on fossil fuels. However, extensive lignin-carbohydrate interactions (LCIs) significantly contribute to the recalcitrance of lignocellulosic biomass, obstructing its efficient fractionation and conversion. Understanding these interactions is critical to comprehensively grasping the mechanisms of intrinsic recalcitrance and formulating strategies to overcome it. In this review, we present an in-depth overview of LCIs, emphasizing the importance of elucidating these interactions to enhance lignocellulose utilization. Unlike previous reviews, we explore both lignin-carbohydrate covalent interactions (LCCIs)—including benzyl ether (BE), <em>γ</em>-ester (GE), and phenyl glycoside (PG) linkages—and lignin-carbohydrate non-covalent interactions (LCNCIs), such as those between lignin and cellulose, as well as lignin and hemicellulose. In addition, we discuss methods for modulating both LCNCIs and LCCIs to improve lignocellulose utilization. Lastly, this review identifies existing challenges and future opportunities in uncovering LCIs, aiming to guide research towards a more comprehensive understanding of the LCI network. The goal is to assist in unleashing the full potential of lignocellulosic biomass across diverse fields, while promoting efficient, environmentally sustainable, and economically viable applications.

However, their densely covalent crosslinked networks present trade-offs between degradation efficiency, selectivity, and scalability for end-of-life recycling, which hinder the retention and reuse of material value. As production and in-service stock continue to grow, end-of-life waste streams are rapidly expanding, exacerbating environmental burdens and the loss of high-value resources. Recycling of thermosets and their composites has therefore become a pressing challenge. This review focuses on the concept of selective bond cleavage strategies and examines two complementary pathways: end-based recycling, which targets the selective deconstruction of existing thermosets and composites, and source-based recycling, which involves designing new resin systems with built-in recyclability. It discusses hydrolysis, alcoholysis, aminolysis, ammonolysis, hydrazinolysis and acidolysis of ester, urea and imide linkages, as well as degradation mediated by strong bases, Lewis and Brønsted acids, and transition metals that cleave C<img>O, C<img>N and C<img>C bonds. The design principles of cleavable or dynamic motifs, together with reversible polymerization and on-demand depolymerization in recyclable thermosets are also summarized. Through a comparative literature analysis, we highlight the trade-off between degradation efficiency and selectivity in end-based recycling and the balance among service performance, processability and deconstruction efficiency in source-based recycling. An application-oriented framework centered on selective deconstruction and efficient reconstruction is proposed, emphasizing the critical roles of mass/heat transfer, solvent and phase behavior, separation and reutilization, process intensification and scale-up, and system-level techno-economic analysis and life cycle assessment.
