Calorimetry studies associated with the curing of DGEBA epoxy with hardener diethanolamine (DEA).  Curing involves a complex series of reactions (including zwitterion formation, 阴离子链生长和终止). 叔胺在初始反应后形成 of the secondary amine to form an adduct acts to open the epoxide ring to form the 然后在链式生长中繁殖的中性离子.  羟基加速了反应.  Currently we are acting to separate contributions by studying DGEBA reaction with 二丁胺和辛醇.

Cure Kinetics of the Tertiary Amine Activated Reaction in DGEBA Epoxy Hardened with 二乙醇胺 ——安西平克(2017)

Thermal and mechanical properties of glasses vary with time as they “age” at temperatures 在玻璃化转变下.  研究了两种环氧树脂.  DGEBA用二乙醇胺腌制 (DEA)和DGEBA用多胺Jeffamine T-403固化.  使用是由简单的理论构成的 of aging (e.g.(KAHR和Eyring模型)来了解老化过程.  特别是 interesting is the effect of compressive stress on the effects of aging, both small, 研究了亚屈服应力和大的屈服后应力.

A problem of long standing interest is how the thickness of a film affects the glass 属性(e.g.、玻璃化转变温度和弛豫行为). Two of us (Curro and McCoy) proposed a 密度泛函理论 based theory of how and Tg 随膜厚变化.  我们和以前的学生史蒂文森合作 用分子动力学模拟来探索这种联系. 目前的工作重点 关于放松时间.
