摘要

在硅橡胶中分别加入2wt%、3wt%和4wt%的纳米al2o3。随着纳米al2o3含量的增加，空间电荷积累和耗散速率增加，载流子迁移率降低，陷阱深度增加。结果表明:纳米al2o3 /硅橡胶复合材料的载流子陷阱比基体材料多，且纳米al2o3填料的陷阱更深;

Effect of nanoparticles loading on space charge characteristic of Al2O3-silicone rubber nanocomposites

2wt%, 3wt% and 4wt% nano-Al₂O₃ was loaded into silicone rubber respectively. The dispersion of particles were observed by TEM, and analyzed by software Image J. With the increase of nano-Al₂O₃ content, both space charge accumulation and dissipation rate increase, carrier mobility decreases, trap depth increases. The results show that nano-Al₂O₃/ silicone rubber composite has more carrier trap than matrix material, and nano-Al₂O₃ fillers bring in deeper traps.
