Effect of ketjenblack and barium titanate on the piezoresistive behaviour of silicone rubber particulate composites

In the present study, silicone rubber reinforced with ketjenblack and barium titanate were fabricated using high temperature compression molding method. These particulate composites are characterized for piezoresistive sensitivity. Ketjenblack conducting dielectric fillers in vulcanized matrix. The effects of fillers, filler loading, amount curing agent, mixing time on properties these investigated. sensitivity recorded maximum values 3.7(10–3) (kPa)−1 dielectric-conductive composites. linear variation normalized resistance change was observed pressure up to 20 kPa. composite increases reduction agent loadings, increasing temperature. depends loading. demonstrate interaction among factors.
