抗静电薄膜的性能和在卫星上的应用

ANTISTATIC FILM'S PERFORMANCE AND ITS APPLICATION TO SATELLITE

本文给出了研制的三种抗静电薄膜系列:ITO、IO、TO的电学、光学性能实测结果。薄膜系用磁控溅射方法在Kapton、Mylar等柔性基底上制备。试验表明导电膜的稳定性很好。同时还进行了模拟亚暴环境下抗静电膜的表面电导测试。结果表明经过改性的柔性二次表面镜可有效地消除静电积累,使电位控制在80V以下。而未经镀敷抗静电膜的柔性二次表面镜,表面充电电位可高达8—10kV。

In this paper, the measured results of the electric and optical performance of ITO, IO and TO films are given. These films are prepared on the substrates of flexible Kapton, Mylar and FEP Teflon by the magnetron sputtering. The tests indicate that their stabilities under various conditions are quite good. The conductivity of the antistatic films in the simulated substorm environment is also measured. The results show that the modified flexible SSM can eliminate the charge accumulation on their surfaces and control the surface voltage below 80 Volt. On the contrary, the potential on the uncoated SSM surface can have a value up to 8 -10 kV.
