Electrical Conductivity Variation With Temperature of Irradiated Standard Malaysian Rubber(SMR)

Abstract

Electrical conductivity variation with temperature in therange (303-368)K during heating and cooling has been studied forirradiated SMR material using Alpha and Beta - particles and Gammarays. It was found that the values of conductivity during cooling arehigher than that during heating for all samples before and afterirradiation. Also it appears that the molecules suffer from crosslinkingduring irradiation with Alpha-particles , while they suffer fi·omdegradation and cross-linking during irradiating with Beta-particles andGamma-rays, depending on the irradiating time.
