Abstract In this study, rationally designed random copolymers containing highly flexible, low glass transition temperature (Tg) segments are suggested as effective polymeric gelators for high-performance ion gel electrolytes. To this end, a series of poly(styrene-ran-butyl acrylate) copolymers (PS-r-PBAs) is prepared by a one-pot reversible additional-fragmentation chain transfer polymerization. Physically crosslinked ion gel electrolytes are produced by self-assembly when blended with ionic liquids of 1-butyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([BMI][TFSI]). The properties of gels based on PS-r-PBAs and PS-ran-poly(methyl methacrylate)s (PS-r-PMMAs) are compared at similar molecular conditions. As a result, the effectiveness of the high chain flexibility of butyl acrylate is shown by higher ionic conductivity. The gels with PS-r-PBAs are further optimized in terms of the molecular characteristics of copolymers (e.g., the content of Sty and total molecular weight) and gel composition. The versatility of PS-r-PBA-containing gels as practical electrolyte platforms is demonstrated by preparing all-in-one type electrochromic devices, for which electrochromic ion gels are prepared by incorporating chromophores into the gels. To extend the functionality of the electrochromic devices, dot-shaped electrochromic gel arrays are fabricated for actively controllable smart windows that can reduce the window strike of birds.

共聚物凝胶剂的链柔韧性对用于功能性电化学装置的离子凝胶电解质性能的影响

摘要 在这项研究中，合理设计的含有高柔性、低玻璃化转变温度 (Tg) 链段的无规共聚物被认为是高性能离子凝胶电解质的有效聚合物凝胶剂。为此，通过单锅可逆附加断裂链转移聚合制备了一系列聚（苯乙烯-ran-丙烯酸丁酯）共聚物（PS-r-PBA）。当与 1-丁基-3-甲基咪唑鎓双（三氟甲基磺酰基）亚胺（[BMI][TFSI]）离子液体混合时，通过自组装产生物理交联的离子凝胶电解质。在相似的分子条件下比较了基于 PS-r-PBA 和 PS-ran-聚（甲基丙烯酸甲酯）（PS-r-PMMA）的凝胶的性质。因此，丙烯酸丁酯的高链柔韧性的有效性通过更高的离子电导率显示出来。具有PS-r-PBA 的凝胶在共聚物的分子特性（例如Sty 含量和总分子量）和凝胶组成方面得到了进一步优化。通过制备一体型电致变色装置证明了含有 PS-r-PBA 的凝胶作为实用电解质平台的多功能性，通过将发色团掺入凝胶中来制备电致变色离子凝胶。为了扩展电致变色装置的功能，制造了点状电致变色凝胶阵列，用于主动可控的智能窗户，可以减少鸟类的窗户撞击。通过制备一体型电致变色装置证明了含有 PS-r-PBA 的凝胶作为实用电解质平台的多功能性，通过将发色团掺入凝胶中来制备电致变色离子凝胶。为了扩展电致变色装置的功能，制造了点状电致变色凝胶阵列，用于可主动控制的智能窗户，可以减少鸟类的窗户撞击。通过制备一体型电致变色装置证明了含有 PS-r-PBA 的凝胶作为实用电解质平台的多功能性，通过将发色团掺入凝胶中来制备电致变色离子凝胶。为了扩展电致变色装置的功能，制造了点状电致变色凝胶阵列，用于主动可控的智能窗户，可以减少鸟类的窗户撞击。
