AI Technical Summary
Existing technologies for developing epoxy resins with high dielectric strength and high glass transition temperature suffer from problems such as long development cycles, high costs, and uncontrollable results. Nano-doping leads to uneven dispersion, affecting electrical, thermal, and mechanical properties.
Using first-principles calculations and molecular dynamics, a high-performance bisphenol A epoxy resin for electrical equipment was designed through simulation. A stable molecular model was established, the bandgap distribution and crosslinking density were optimized, and the epoxy resin model with the widest bandgap and the highest crosslinking density was selected.
We rapidly developed epoxy resins that combine high dielectric strength and glass transition temperature, significantly shortening the R&D cycle and reducing costs. We also verified their performance through simulation calculations, ensuring the reliability of molecular structure control.
