防静电工作表面：发展和历史（五）

ESD Work Surfaces：Developments and History

提供静电放电能力的另一个材料途径是在塑料材料中混入导电填充物。早在二战时期，德国潜艇使用导电炭填充橡胶覆盖其通气管来躲避雷达探测。导电炭黑改变了橡胶的特性，可以有效地对付当时最先进的500MHz频率探测。导电填充物的使用也应用到静电放电应用中。控制静电的进一步努力在20世纪50年代后期和60年代初被报道，

Another materials approach to provide ESD capabiliDT is to incorporate conductive fillers into plastic materials. As early as World War II, German U-boats employed conductive carbon filled rubber coverings on their snorkels to elude radar detection. The conductive carbon black modified the electrical characteristics of the rubber sufficiently to make it effectively against the state-of-the- art 500 MHz sensing.
