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.

含二元碳纳米填料的聚丙烯组合物的制备与性能
摘要利用甲基铝氧烷活化的均相异茂金属催化剂 rac-Me2Si(2-Me-4-PhInd)2ZrCl2,通过原位聚合合成了基于聚丙烯和二元碳纳米填料(石墨烯颗粒和单壁碳纳米管)的复合材料。二元碳纳米填料的使用提高了热稳定性和抗热氧化降解能力,并影响了合成材料的反射率和其他电学特性。研究表明,二元纳米填料可对聚丙烯的热氧化产生协同效应。在石墨烯纳米片中引入即使是少量的单壁碳纳米管,也会显著降低所得复合材料的反射系数。
