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.

Influence of blend ratio on the electrical characteristics of vulcanized SBR/NBR blends compatibilized by Cis-polybutadiene rubber

et al. 2018

B LENDS composed of styrene butadiene rubber (SBR) and acrylonitrile-butadiene rubber (NBR) have been fabricated by melt-blending technique using two-roll mill blend machine. Cis-polybutadiene rubber (CBR) was used as a compatibilizer for enhancing the homogeneity between blend phases. No previous reports were found to discuss improving electrical properties of vulcanized SBR/NBR blends using unfilled rubber system (i.e. no fillers incorporation). SEM micrographs were utilized to verify the compatibility between two rubber ingredients in various blends, owing to the use of compatibilizer. Thermal stability of blends was investigated by differential thermal analysis (DTA) and differential scanning calorimetric (DSC) to evaluate the influence of blend ratio on the compatibility of investigated samples. Results revealed that the dielectric properties of blends are dramatically influenced by altering the blend ratio. The results revealed that the SEM observations confirmed the compatibilization effect of CBR on vulcanized SBR/NBR blends. Meanwhile, thermal properties of vulcanized SBR/NBR blends were enhanced with increasing of SBR contents in blends. The complex impedance graphs showed circular arcs showing the bulk contribution to overall electrical behavior for investigated vulcanized SBR/NBR blends. During I-V characteristics have been presented, where a remarkably change from linear behavior to nonlinear conduction at lower temperatures was found for 0SBR/100NBR blends. These findings supported and confirmed that the compatibilization effect and the blend ratio between rubber compositions have strongly influenced on their thermal and electrical properties of vulcanized blends.
