포도당 환원제와 PdCl2촉매를 사용한 무전해 은도금 PET 직물의 제조

Abstract

The purpose of this study is to propose the development of high quality electromagnetic wave shielding fabrics. Silver nitrate is used for polyester fabric as an electromagnetic wave shielding material. The effects of activators and electroless silver plating condition on the evenness and adhesion of silver to fabrics, are observed through the SEM micrographs. Surface morphology and wash-ability are measured using SEM. The results are as follows: The optimum weight loss by alkaline hydrolysis of polyester fabrics is about 20%. The optimum concentration of SnCl2 and PdCl2 in catalyst reaction using PdCl2 as an activator is 2.5g/L and 0.5g/L, respectively. The optimum concentration of dextrose to improve adhesion between the silver plating and fabrics is 45g/L. The optimum concentration of silver nitrate in the catalyst reaction, using PdCl2 as an activator is 56 g/L, respectively. The optimum plating temperature and time are 15oC and 30minutes, respectively.
