摘要: Thermostable nanocomposites based on interpenetrating polymer network bismaleimide/cyanate ester (BMI/CE) copolymer, derived from bisphenol A dicyanate, 4,4′-bismaleimidodiphenyl methane, and doped by 1–5 wt% organo-modified 2D montmorillonite (OMMt) nanoparticles were synthesized characterized using a dielectric strength tester, concept 40 impedance analyzer, scanning electron microscope (SEM), dynamic mechanical analysis, thermogravimetric analysis techniques. OMMt improves the dispersibility, alignment interfacial of these nanocomposites, electrical conductivity increase with increasing loading, suitable addition can enhance properties property BMI/CE copolymer. SEM shows distinct characteristics ductile fracture blends. In addition, OMMt/BMI/CE have better thermal stability higher compared to those resin content. All changes in are closely correlated which could form an interaction interface structure system.
