Synthesis and Conductivity of Natural Rubber, Butadiene Rubber and Butadiene-co-styrene Rubber Solutions Containing NaClO4 and Active Carbon

Abstract

Natural rubber (NR), butadiene rubber (BR) and styreneco- butadiene rubber (SBR) dissolved in toluene as solvents gains electrolytic properties after the addition of NaClO₄. Active carbon was also added to this polymer in order to improve its conductivity. The conductivity of the NR system with NaClO₄ and active carbon is equal to 4 × 10^-6 S cm^-1, while that of the BR system with NaClO4 and active carbon is equal to 5.8 × 10-5 S cm-1; however, the conductivity for the SBR system with NaClO₄ and active carbon is 7.7 × 10^-5 S cm^-1 at a temperature of 293 K and a frequency of 10 kHz. The electrolytes were tested within a conductivity range of 1 to 25 kHz. These polymer electrolyte systems can find application as materials for anticorrosive and antielectrostatic protection in tanks designed for fuel and inflammable liquids.
