摘要

以聚酰胺酸前驱体与多壁碳纳米管(MWNTs)为原料,通过超声共混和原位聚合制备了聚酰亚胺/多壁碳纳米管杂化膜。用SEM对膜的表面形貌进行了表征。研究了纳米碳管对电性能的影响,结果表明,随着纳米碳管含量的增加,纳米碳管的体积电阻率下降。杂化膜的电晕电阻高于纯聚酰亚胺膜,其时间为4h。当MWNTs掺杂量接近0.34wt%时,电晕电阻时间达到最大值7.75h。

Study on preparation and electrical properties of polyimide/Multi-walled carbon nano-tubes films
In the paper, polyimide/Multi-walled carbon nano-tubes hybrid films were prepared from polyamide acid precursor and Multi-walled carbon nano-tubes (MWNTs) through ultrasonic blending and in-situ polymerization. The surface morphology of the films was characterized by SEM. The influence of MWNTs on the electrical property was researched, which showed that with the increasing content of MWNTs, the volume resistivity declined. The corona-resistance of the hybrid films was higher than the pure polyimide films which time was 4h. When the doping content of MWNTs was near to 0.34wt%, the time of corona-resistance reached the maximum of 7.75h.
