Abstract
Composites based on polypropylene and binary fillers (graphene particles together with carbon nanotubes) are synthesized by in situ polymerization with the use of a homogeneous isospecific metallocene catalyst rac-Me2Si(2-Me-4-PhInd)2ZrCl2 activated by methylaluminoxane. The application of binary carbon nanofillers allows one to enhance thermal stability and thermo-oxidative resistance of materials and to decrease the percolation threshold. It is shown that a close level of conductivity is achieved in the case of a binary filler at a significantly lower concentration. The resulting polymer composites can be applied as antistatic materials, shields and filters of electromagnetic radiation of the corresponding range, and semiconducting layers in power cables.
