Development of Shielding Materials and Protective Clothing for Electromagnetic Waves(I) - Comparison of Conductive Coating and Non-electrolytic Plating -
전자파 차단 의류소재 및 방호복 개발(I) -전도성 코팅법과 무전해 도금법의 비교-
Abstract
Two types of EMI shielding techniques-conductive coating with binder and non-electrolytic plating-were compared. The results showed that non-electrolytic plating was the more effective technique in terms of EMI SE and fabric property. Non-electrolytic plating technique contained multi-step processes; surface conditioning, etching, neutralization, acceleration, plating, and washing. Among them, the surface activation conditions were varied and the effects of etching conditions and catalyst accelerators were studied. Overall, the results indicated that acid etching resulted in higher SE values in the broad frequency range than alkali etching. For a catalyst activator, SnCl
