Abstract

Epoxy resins are an important class of thermoset resins, which are obtained by curing reactions between an epoxy compound and a curing agent. The reaction leads to the formation of a complicated three-dimensional network that extends through the entire system. Thus, as the condition of the curing reaction changes, the resultant network structure does, generally resulting in the change in the bulk glass transition temperature (Tg) of the resultant resin. In this short review, we briefly summarize how the curing condition affects the formation of the network structure and thereby alters the bulk Tg.

固化工艺对环氧树脂玻璃化转变温度的影响

环氧树脂是一类重要的热固性树脂，它是由环氧化合物和固化剂之间的固化反应得到的。这种反应导致了一个复杂的三维网络的形成，并延伸到整个系统。因此，随着固化反应条件的变化，生成的网络结构也会发生变化，一般会导致合成树脂的体玻璃化转变温度(Tg)发生变化。在这篇简短的综述中，我们简要地总结了固化条件如何影响网络结构的形成，从而改变Tg的体积。

期刊介绍： For the communication among the members, the journal of the Society of Rheology Japan, NIHON REOROJI GAKKAISHI (5 issues per year), was established in 1973 and it is the oldest journal on rheology in Asia. The journal contains original and review articles on rheology and related topics, information for all SRJ events, and reports of domestic/overseas meetings. Articles in Japanese as well as in English are considered for publication, not only from the members but also from the researchers outside. Papers from new emerging areas of the field are particularly welcome. The electronic version of the articles is available via the internet with an open access policy.
