Corona Resistance of Direct Flourinated Epoxy/Al

摘要

nanoparticles yet fluorination leads to decreasing of permittivity. Results of surface potential decay and surface morphology measurement indicate that combination of fluorination and nano filling significantly improves corona resistance of epoxy resin. Charge injection to sample matrix tends to be restrained by high surface conductivity of fluorinated layer, while nanoparticles may attenuate the mean kinetic energy of negative charge carriers that arriving sample surface, and increase the probability of charge being captured in matrix. In addition, the high bond energy of C-Fx groups and Al
