The invention discloses a lunar landing suit dust removal system based on an electret and a dust removal method of the lunar landing suit dust removal system. An electret friction high-voltage generation module is arranged on the inner layer of the lunar landing suit, and a polarized electret is rubbed by movement of an astronaut to generate a corresponding low-energy high-amplitude voltage pulse to excite an embedded flexible electrode module on the outermost layer of the lunar landing suit to create a strong alternating standing wave electric field to expel charged lunar dust; for small-particle charged lunar dust, stripping polarization charges are generated on a bipolar electret film through a stripping polarization effect, and residual charged lunar dust is removed by utilizing a power-supply-free uniform electric field created between the bipolar electret and an electrode array; according to the invention, charged lunar dust can be removed with low power consumption, high static safety and wide coverage area, secondary adhesion of the charged lunar dust can be prevented, and the device has the characteristics of good stability, high applicability and the like, and is suitable for removing and protecting the charged lunar dust adhered to the surface of the lunar landing suit.
本发明公开了一种基于驻极体的登月服除尘系统及其除尘方法。本发明在登月服内层设置驻极体摩擦高压发生模块,利用宇航员运动摩擦极化驻极体,产生相应的低能量高幅值电压脉冲激励登月服最外层嵌入式柔性电极模块营造强交变驻波电场驱离带电月尘;对于小颗粒带电月尘,通过剥离极化效应在双极性驻极体体膜产生剥离极化电荷,利用双极性驻极体与电极阵列间营造的无电源均匀电场清除残留带电月尘;本发明能够实现低功耗、高静电安全和覆盖面积广地清除带电月尘,还能够防止带电月尘二次黏附,具有稳定性好和适用性高等特点,适用于登月服表面黏附带电月尘的清除与防护。
