本文简单地描述了高聚物驻极体的制备,荷电性能和荷电机理并对驻极体的表面电荷及其寿命作了测定。高聚物驻极体用于临床治疗冻疮、关节酸痛和疖子有较好的疗效。 This article briefly describes the preparation of polymer electrets, charging performance and charging mechanism and the surface charge of electrets and their lifetime were determined. Polymer electret for the clinical treatment of frostbite, joint pain and prickly heat have a better effect.
