Abstract

A tetrafunctional glycidyl ether cyclic siloxane epoxy resin (TGTS) has been synthesized, characterized and cured with four aromatic amine hardeners: 1,3-phenylenediamine (PDA), diethyltoluenediamine (DETDA), 4,4-diaminodiphenylmethane (DDM) and 1,3-bis(4-aminophenoxy)benzene (APB). Each of the cured networks produces transparent and homogeneous networks, although when TGTS is cured with DETDA, reduced compatibility led to lower epoxide consumption, a more heterogenous microstructure and deleterious effects upon properties. Reduced miscibility of DETDA significantly impacts the chemical structure and microstructure of the network, resulting in significant reductions in thermal and mechanical properties but higher UV-A transmission. The PDA-, APB- and DDM-cured networks conversely were more miscible and display properties typical of organic–inorganic hybrid networks, such as good mechanical properties at ambient and sub-ambient temperatures, comparatively high glass transition temperatures, improved resistance to oxidation and lower UV-A transmission. © 2024 The Author(s).

环硅氧烷四官能缩水甘油醚树脂衍生的无机-有机聚合物网络
我们合成了一种四官能团缩水甘油醚环硅氧烷环氧树脂(TGTS),对其进行了表征,并用四种芳香胺固化剂进行了固化:1,3-苯二胺(PDA)、二乙基甲苯二胺(DETDA)、4,4-二氨基二苯基甲烷(DDM)和 1,3-双(4-氨基苯氧基)苯(APB)。每种固化网络都能生成透明、均匀的网络,但当用 DETDA 固化 TGTS 时,相容性降低导致环氧化物消耗量减少,微观结构更不均匀,并对性能产生有害影响。DETDA 的混溶性降低会严重影响网络的化学结构和微观结构,导致热性能和机械性能显著降低,但紫外线-A 透射率更高。相反,PDA、APB 和 DDM 固化网络的混溶性更高,并显示出有机-无机混合网络的典型特性,如在常温和亚常温下具有良好的机械特性、相对较高的玻璃化转变温度、更好的抗氧化性和更低的紫外线-A 透射率。© 2024 作者。国际聚合物》由 John Wiley & Sons Ltd 代表化学工业协会出版。
