Influence of Grafting of a Polymeric Antistatic Membrane Doped with Orthophosphoric Acid on its Electrical Properties

Polyvinyl chloride (PVC)/styrene‐butadiene rubber (SBR) antistatic membranes were prepared by two types of grafting, namely, self‐ and chemical grafting processes, using solvent‐casting technique via tetrahydrofuran and toluene as solvents for PVC and SBR, respectively. The membrane modification was carried out by doping orthophosphoric acid (OPA) in the polymer solution. The effect of OPA on the properties of the PVC/SBR membranes was studied in detail with respect to the electrical properties of the antistatic membranes. The electrical conductivities were improved by increasing the OPA content onto membranes. These results suggest that PVC/SBR antistatic membranes doped with OPA can be utilized as promising antistatic material candidates for fabrication of automobile tires and electronic materials. The influence of self‐ and chemical grafting initiation processes of prepared polyvinyl chloride/styrene‐butadiene rubber antistatic membranes doped with orthophosphoric acid on their physical and electrical properties was evaluated. These membranes with enhanced alternating current and direct current conductivity are promising antistatic material candidates for automobile tire fabrication and electronic materials.
