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。
