Abstract

Studied are the film composite materials based on the polymer polybenzimidazole matrix with nano-structured carbon fillers. As a matrix the poly[2,2’-(p-oxydiphenylen)-5,5’-bisbenzimidazole] (OPBI) has been used. Graphite nanoplates and few-layered graphene were applied as the fillers. Piezoresistive effect in the film composite samples, strain gauge factor and endurance were studied experimentally. It is shown that the strain gauge factor does not depend on the concentration of filler and, on the average, equal 15 (for FLG composites) and 13 (for GNP composites) within the error. It was found that strain gauge factor of the samples does not change up to 100,000 alternating loading cycles. Temperature dependences of electrical resistance of composite samples have been measured and analyzed. It has been established that the main insulating polymer gaps between the carbon filler nanoparticles make the main contribution to the electrical resistance and conduction mechanism is tunneling between the particles
