Preparation and Properties of Polypropylene Compositions with Binary Carbon Nanofillers

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 -Me 2 Si(2-Me-4-PhInd) 2 ZrCl 2 activated by methylaluminoxane. The use o...

Description
Summary: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 -Me 2 Si(2-Me-4-PhInd) 2 ZrCl 2 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.
