Characteristics, Nano-Dispersibility and Application of Conducting Polypyrrole Inserted into Nitrile Rubber by Single-Step in situ Polymerization

In this paper, we prepared nitrile rubber (NBR) and polypyrrole (PPy) as conductive fillers of electrical conductive composites to improve their electrical resistivity and mechanical properties and application by single-step of in situ polymerization. Further, we discussed the optimization condition, nano-dispersibility, and physical characteristic such as thermal-stability, electrical resistivity, mechanical and morphology of vulcanized PPy/NBR conducting composites. The composites showed that PPy-particles uniformly dispersed in the NBR matrix. Optimum volume resistivity is 2 × 107 Ω-square, and the tensile stress changes from 3.93 N/mm2 to 67.35 N/mm2. We expect that efficiencies of NBR/PPy composites can be applied to develop conducting printing rollers.
