摘要

硅橡胶被广泛用作室外保温结构。本文研究了硅橡胶氧化铝纳米复合材料在水扩散作用下的性能。采用不同重量百分比的纳米氧化铝制备了硅橡胶纳米复合材料。研究了基本表面电位衰减以及电荷阱特性，并使用FTIR分析来评估可能由于吸湿而产生的官能团变化。研究结果表明，水扩散纳米复合材料表面电位衰减率增加，电荷阱深度变化。结果表明，5 wt. %氧化铝增强硅橡胶纳米复合材料的性能较好。

Analysis of Surface Potential Decay and Charge Trap Characteristics of Water Diffused Silicone Rubber Nanocomposites

Silicone rubber is extensively used as outdoor insulation structure. In the present study the performance of silicone rubber alumina nanocomposite is analysed under water diffusion. Silicone rubber nanocomposites were prepared with different weight percentages of nano alumina. The fundamental surface potential decay along with charge trap characteristics were studied and FTIR analysis is used to evaluate change in functional groups that may arise as a result of moisture absorption. The results of the study indicate an increase in surface potential decay rate and variation in the charge trap depth with water diffused nanocomposites. The results show that 5 wt. % alumina reinforced silicone rubber nanocomposite specimen has performed better.
