In this study, conductive polyaniline (PANI) ribbons were introduced to a semiconductive layer to improve the conductivity stability of the layer during thermal expansion and enhance its ability to inhibit charge injection into the insulating layer. To maximise the effect of PANI, PANI and carbon black (CB) were preformed into a uniformly dispersed composite, which was then added to the polymer matrix of the semiconductive layer. The experimental results show that the resistivity of the semiconductive layer containing the PANI/CB composite is more stable during thermal expansion than that of the semiconductive layer only doped with CB. This is attributed to the conductive CB network being enhanced by the PANI ribbons. In addition, due to the unique conductivity mechanism and high dielectric constant of PANI, the semiconductive layer has a strong ability to inhibit space charge injection into the insulating layer.

导电聚苯胺/炭黑复合材料对半导体层性能的影响

在这项研究中，将导电聚苯胺 (PANI) 带引入半导体层，以提高该层在热膨胀过程中的导电稳定性，并增强其抑制电荷注入绝缘层的能力。为了最大限度地发挥 PANI 的效果，将 PANI 和炭黑 (CB) 预制成均匀分散的复合材料，然后将其添加到半导体层的聚合物基质中。实验结果表明，含有PANI/CB复合材料的半导体层在热膨胀过程中的电阻率比仅掺杂CB的半导体层的电阻率更稳定。这归因于 PANI 带增强了导电 CB 网络。此外，由于聚苯胺独特的导电机制和高介电常数，
