HYGROSCOPIC NATURE OF ANTISTATIC COATING : CRT TECHNOLOGIES II

概要

論文の詳細を見る
With incresing demands on antistatic properties of CRTs, which will eliminate electrical shocks due to static charge built up especially under low humidity environment, tremendous efforts were made to investigate means of fast discharging. While most of the studies were concentrated on conductive metal ion type (such as Li) or semiconductor type (such as ITO) coatings, very few studies have been conducted to investigate the true mechanisms of hy groscopic type antistatic effect. Published literatures suggested that, under hygroscopic mode, antistatic properties come from the adsorption of moisture from air at the surface of coating due to the presence of hygroscopic ions. Based on this hypothesis, antistatic properties will disappear if this type of hygroscopic ion is absent. However, in this paper, some controversies were observed in our results, and discussion will be made based on these
