摘　　要：防静电热控材料是航天器上常用的热控材料之一,其在空间环境下的性能退化是航天器设计中必须考虑的问题。对几种航天器上常用的防静电热控材料进行了低能质子辐照试验,并原位测量样品的太阳吸收率和表面电阻率,对低能质子辐照下的性能退化规律进行了初步分析。试验结果表明,在低能质子辐照下,这3种材料的太阳吸收率都有不同程度的上升,而表面电阻率则呈现下降的趋势。Anti-electrostatics thermal, control material is one of the materials commonly used for spacecraft. Its degradation performance in space environment is of concern for spacecraft designers. Several anti-electrostatics thermal control materials were exposed under low energy proton radiation and its solar absorptance and surface resistivity was measured in-situ. The test results was analyzed and the results showed that solar absorptance of the three types of thermal control materials increased after Iow energy proton exposure, but the surface resistivity appear a descend trend.
