Abstract

Composition and heating rate dependences of the surface resistivity versus temperature behavior were studied for epoxy resin composite thin films containing conducting ceramics filler. For all compositions studied (10.5-15.2 vol% filler), the anomalous positive-temperature-coefficient-of-resistivity (PTCR) effect was observed above the glass transition temperature of the matrix. The heating rate dependence of the PTCR behavior was examined. The magnitude of the PTCR effect decreased with decreasing the heating rate. Such a heating rate dependence of the PTCR magnitude became obvious as the filler volume fraction increased.
