Abstract
Composites based on polypropylene and binary carbon nanofillers (graphene particles and single-walled carbon nanotubes) have been synthesized by in situ polymerization using the homogeneous isospecific metallocene catalyst rac-Me2Si(2-Me-4-PhInd)2ZrCl2 activated by methylaluminoxane. The use of binary carbon nanofillers increases thermal stability and resistance to thermo-oxidative degradation and affects the reflectance and other electrical characteristics of synthesized materials. It has been shown that the binary nanofillers can have a synergistic effect on the thermal oxidation of polypropylene. The introduction of even a small amount of single-walled carbon nanotubes into graphene nanoplatelets significantly reduces the reflection coefficient of the resulting composite materials.
期刊介绍:
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
