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.
