| 摘 要： | 文章通过试验研究了近紫外辐照前后的真空环境对防静电热控涂层的电学性能影响,探讨了真空环境对防静电热控涂层电学性能影响的机理,给出了地面模拟试验过程中关于数据分析的建议.研究发现:真空环境将引起防静电热控涂层的表面电阻率降低、导电性能增强,而氧空位的增加和吸附氧的释放则是其表面电阻率降低的主要原因.

| Abstract: | This paper studies the influence of vacuum environment on electrical properties of antistatic thermal control coatings by experiments and analysis of the influence mechanism.Some proposals are made on the data analysis of ground simulation tests for antistatic thermal control coatings.It is shown that the surface resistivity of antistatic thermal control coatings will decrease in the vacuum condition due to the increase of oxygen vacancies and the release of adsorbed oxygen. |

| Keywords: | vacuum electrostatic protection thermal control coating electrical property |
