Abstract

Charge formation in epoxy loaded with fillers such as SiO2, CaCO3 and Al(OH)3 was investigated. A small amount of homocharge was observed in the cured epoxy. The homocharge in epoxy/filler composite increased when both SiO2 and Al(OH)3 are mixed, whereas it decreased when CaCO3 is mixed. The highest homocharge was found in the epoxy containing 50 phr of SiO2. Space charge characteristics did not change by the surface treatment of SiO2 with γ-glycidoxypropyltrimethoxysilane, a coupling agent, although diffused charge distributions were observed at some contents of coupling agent. Homocharge accumulation in these samples was attributed to the trapping of injected electrons at the epoxy/filler interfaces.
