Abstract

In this study, we prepared a polyhedral oligomeric silsesquioxane (POSS)-linking polyamide (POSS polyamide) by a polycondensation of ammonium-functionalized POSS (POSS-A) and carboxyl-functionalized POSS (POSS-C) in dehydrated dimethyl sulfoxide (DMSO) using 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) and -hydroxysuccinimide (NHS) as condensing agents. The obtained POSS polyamide was soluble in various highly polar solvents, and it could form a self-standing film. FT-IR, H NMR, and Si NMR analyses showed that POSS polyamide is a polymer in which POSS-A and POSS-C are linked almost linearly by amide bonds. Furthermore, the cast film obtained by heat-treating the polymer at 150 °C for 30 min exhibited excellent transparency and hard-coating (pencil scratch test: 5H) and antifogging properties (evaluation by water vapor exposure).

摘要

在本研究中，我们以1-(3-二甲基氨基丙基)-3-乙基碳二亚胺盐酸盐（EDC）和N-羟基琥珀酰亚胺（NHS）作为缩合剂，在脱水二甲基亚砜（DMSO）中，通过铵官能化倍半硅氧烷（POSS-A）与羧基官能化倍半硅氧烷（POSS-C）的缩聚反应制备了一种多面体低聚倍半硅氧烷（POSS）连接的聚酰胺（POSS聚酰胺）。所制备的POSS聚酰胺可溶于多种高极性溶剂，并且能够形成自支撑膜。傅里叶变换红外光谱（FT-IR）、氢核磁共振（¹H NMR）和硅核磁共振（²⁹Si NMR）分析表明，POSS聚酰胺是一种聚合物，其中POSS-A和POSS-C通过酰胺键几乎呈线性连接。此外，将该聚合物在150℃下热处理30分钟得到的流延膜表现出优异的透明度、硬涂层性能（铅笔划痕试验：5H）和防雾性能（通过水蒸气暴露进行评估）。
