| 目的 研究多因素条件下航天用典型介质材料聚酰亚胺表面充电特性。方法 利用空间介质材料表面带电地面模拟实验系统，以电子枪辐照材料模拟空间带电环境中航天器材料表面带电过程，以航天器上常用的介质材料聚酰亚胺为研究对象，研究不同电子能量、不同束流密度和不同厚度下聚酰亚胺表面充电特性。结果 聚酰亚胺表面电位随着电子能量、束流密度和厚度的增大而增大，电子能量越高，束流密度越大，聚酰亚胺表面充电平衡时间越短。结论 航天器介质材料表面带电程度与空间带电环境的电子能量、束流密度和介质材料本身结构紧密相连，研究多因素作用下航天用典型介质材料表面充电特性，将为航天器带电防护设计提供数据支持。 |

| Objective To study surface charging characteristics of Kapton material used typically on spacecraft under multifactor. Methods The experimental system was simulated through surface charged ground of space material. The surface charging process of spacecraft in charged environment was simulated with electron gun irradiation material. Surface charging characters of Kapton with different electron energy, flux density and thickness usually used as dielectric material in spacecraft were researched. Results The surface potential of Kapton increased with the increase of electron energy, flux density and thickness; the larger the electron energy and the flux density were; the shorter the charging balance time of the Kapton surface was. Conclusion The charging level of the spacecraft material’s surface is connected tightly with the electron energy and flux density of the charged space environment and the structure of the dielectric material. Research on charging characteristics of the Kapton material provides a data support for designing the spacecraft charging protection. |
