The present paper is devoted to the analysis of dielectric properties
of Natural Rubber/Chitosan blends. Natural rubber has excellent
electrical properties like low dielectric constant, loss factor and high
volume resistivity and is used as high frequency insulators. Chitosan
has moderate insulating properties and good oil resistance. Therefore,
by blending natural rubber with chitosan, material with improved
electrical properties can be achieved. In this paper we have studied
the effect of blend ratio, dynamic vulcanization with 2 pphr dicumyl
peroxide and maleic anhydride compatibilization on dielectric
constant, loss factor, volume resistivity and ac conductivity of NR/CS
blends.
