Effect of nanoclay on carbon black reinforced blend of amorphous–semicrystalline polymers

Abstract

In this work, the effect of nanoclay in carbon black reinforced PC-PBT has been investigated on the basis of changes in their mechanical and thermal properties. It has been believed on the basis of FESEM images that CB supports for the expansion of PBT rods and PC wraps around these expanded rods. However, the effect of reinforcing filler for improvement in mechanical properties has been found insignificant which may be due to the agglomeration of reinforcing particles. Addition of nanoclay in carbon black reinforced PC-PBT composite blend shown considerable improvement in its tensile strength (113%). This should be due to the improved dispersion of CB in polymer matrix and better linked-up structure of PBT rods after addition of NC. In addition, this combination has shown simultaneous improvement in tensile strength and ductility which is unusual and may be desirable in many structural applications.
