Study on the Construction Method of Epoxy Resin Crosslinking Model

Epoxy resin has been widely used in the field of high-voltage insulation because of its excellent insulation, heat resistance and mechanical properties. The performance of epoxy resin is closely related to its microscopic molecular composition and cross-linked structure. The use of molecular dynamics simulation methods can carry out structural design, formula screening and performance analysis of epoxy resin materials from a microscopic perspective. This chapter systematically introduces the current research status of molecular simulation of epoxy resin, principles of cross-linking model construction, and modeling calculation methods. And further combined with cases, the research method of using molecular dynamics simulation technology to carry out monomer selection, structure optimization and molecular modification of epoxy resin cross-linked systems was introduced. This chapter aims to summarize the modeling and calculation methods of epoxy resin cross-linked molecular models, point out the advantages of molecular dynamics simulation in the research of epoxy resin, and promote its application in the field of epoxy material research.
