Initially, a water-soluble polyamic acid (PAmA) solution was synthesized utilizing ethylenediaminetetraacetic dianhydride and 2,2-(ethylenedioxy)bis(ethylamine). The incorporation of ether linkages and amic acid functional groups into the polymer backbone generates numerous polar sites, thereby facilitating the formation of a stable aqueous organosilane dispersion predominantly composed of 3-glycidoxypropyl trimethoxysilane (GPTMS), without the use of surfactants or additional salts. Additionally, 25 wt % of GPTMS can be replaced with tetraethyl orthosilicate (TEOS), which serves primarily as a crosslinking agent and a precursor for nanosilica, resulting in an aqueous organic/inorganic dispersion under optimized conditions. Comparative analyses with reference samples, such as polyacrylic acid dispersion, demonstrated a higher degree of condensation of 94.6% for the organic/inorganic dispersion in PAmA, as confirmed by Raman spectroscopy and <sup>29</sup>Si-NMR following sol-gel reactions. These results indicate the formation of extensive cross-linking sites and a silica network, which serves as passive layers, yielding a thermal decomposition temperature exceeding 380 °C for the organic/inorganic layer produced by the PAmA polymer. Notably, the application of the PAmA solution not only enhanced cross-linking density and facilitated the formation of a silica network for the organic/inorganic dispersion but also provided the formation of imide structures, leading to a robust sol-gel-derived hybrid coating system, consistent with findings from FTIR and DSC analyses.

Eliminating various impurities toward the absolute purification of reagents and vessels is a prerequisite for living polymerization. Conventional purification methods are laborious and highly specific for the reagents, significantly limiting the potential of the anionic polymerization. Herein, we develop a facile and universal purification method by the anionic initiating scavenger resin that eliminates impurities via self-sacrificial reactions, substantially simplifying the process. For representative synthesized homopolymers, the degree of polymerization (DP) shows a strict linear correlation with monomer/initiator molar ratios (R) according to DP = R while maintaining low dispersity indices (<i>Đ</i> ≈ 1.03). The living anionic polymerization also enables scalable production of nearly uniform copolymers through designed one-batch sequential polymerization. This large-scale synthesis of composition-controlled polymers with a narrow distribution advances the fundamental understanding of structure-performance relationships and supports the precise construction of uniform self-assembled nanostructures.</p>","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 10","pages":"6493–6499 6493–6499"},"PeriodicalIF":4.4,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114559","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}
