Changes in the Electrical Conductivity of Polypropylene Modified with Nanoparticles of Oxide Compounds
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques ( IF 0.5 ) Pub Date : 2022-06-28 , DOI: 10.1134/s1027451022030284

Abstract

The paper presents the results of studying the effect of modifying polypropylene with nanoparticles of Al2O3, SiO2 and TiO2 on the electrical conductivity before and after irradiation with an electron beam (E = 30 keV, Φ = 2 × 1016 cm–2). A technique for manufacturing nanocomposites based on polypropylene with the addition of nanoparticles is described. As a result of the studies, an increase in the electrical conductivity up to 34% is revealed with the introduction of nanoparticles into the bulk of the polymer. Irradiation with a flow of charged particles also leads to a slight increase in the electrical conductivity, by 5–6%. Such materials are used in electromagnetic-radiation shielding and antistatic coatings of devices.

氧化物纳米粒子改性聚丙烯的电导率变化

摘要

研究了Al 2 O 3、SiO 2和TiO 2纳米粒子改性聚丙烯对电子束辐照前后电导率的影响( E  = 30 keV, Φ = 2 × 10 16 cm –2)。描述了一种制造基于聚丙烯并添加纳米颗粒的纳米复合材料的技术。作为研究的结果,随着将纳米颗粒引入聚合物主体中,电导率增加了高达 34%。带电粒子流的辐照也导致电导率略有增加,增加了 5-6%。这种材料用于设备的电磁辐射屏蔽和抗静电涂层。
