交联度对环氧树脂热导率和力学性能的影响
Thermal Conductivities and Mechanical Properties of Epoxy Resin as a Function of the Degree of Cross-linking
摘要：
环氧树脂是广泛用于许多应用的聚合物基质。尽管取得了重大进展，但充分利用这些材料所需的分子水平知识基础仍然有限。在分子水平上更深入地理解环氧树脂的结构/性能关系对于这些工作的进展至关重要。仅仅根据实验来阐明这些关系，即使不是不切实际，也是很费力的。在这里，分子动力学模拟是用来计算和比较的导热系数和机械性能的一个范例环氧树脂，双酚F交联与二乙基甲苯二胺，揭示这些相互关系。环氧树脂的弹性模量和热传输都显示出随着交联的增加而增加。具体而言，分解成不同的力贡献的热导率表明，键合项有助于增加热通量。这些结果为设计和制造具有理想的热性能和机械性能的定制环氧树脂提供了基础。
英文摘要：
Epoxy resins are widely used polymer matrices for numerous applications. Despite substantial advances, the molecular-level knowledge-base required to exploit these materials to their full potential remains limited. A deeper comprehension of structure/property relationships in epoxy resins at the molecular level is critical to progressing these efforts. It can be laborious, if not impractical, to elucidate these relationships based on experiments alone. Here, molecular dynamics simulations are used to calculate and compare thermal conductivities and mechanical properties of an exemplar epoxy resin, Bisphenol F cross-linked with Diethyl Toluene Diamine, revealing these inter-relationships. Both elastic modulus and thermal transport of the epoxy resin show an increase with greater cross-linking. Specifically, decomposition of the thermal conductivity into different force contributions suggests that the bonded term contributes to an increase in the heat flux. These outcomes provide a foundation for designing and fabricating customized epoxy resins with desirable thermal and mechanical attributes.
