摘要
本文针对空间高能电子环境造成的星内静电放电,开展防护涂层技术研究,为星内带电防护提供新的途径。在常用的聚氨酯三防漆内加入酸掺杂聚苯胺(PAN)纳米颗粒,获得电导率可控的防护涂层材料,将不同电导率的防护涂层样品在电子能量1.2MeV的条件下进行模拟试验,通过比较相同辐照时间内的放电次数,来验证防护涂层的效果。随着PAN的含量增加,防护涂层的电阻率明显下降,添加5%的PAn的防护涂层电阻率下降4个数量级,达到1.16×1011Ω.cm。在相同试验条件下,有防护涂层的样品与未防护样品的放电次数比为1:17。得到结论:通过添加聚苯胺可明显降低三防漆电阻率,对星内静电放电的防护效果显著。
The purpose of this study was to research a new conformal coating technology for the mitigation of the internal electrostatic discharging(IESD).Controlled resistance conformal coating is obtained by introducing polyaniline(PAN)doped acid nano materials into the polyurethane coating.The conformal coating samples with different resistivity were exposed in 1.2Me V electrons.The mitigation capacity of the coating is tested by measuring the discharging times of the samples.The resistivity of new coating decrease with the amount of PAN increase.When the amount of PAN is 5%,the resistivity of coating would be 1.16×1011Ω.cm,four orders of magnitude lower than the conformal coating.At the same experiment condition,the discharging ratio of sample with coating and sample without coating was 1:17.The new coating resistivity decrease by introducing PAN into the conformal coating.The new coating has remarkable property in mitigation of the internal electrostatic discharging.
