PET 직물에 무전해 은도금시 전처리의 영향 = Effect of Pretreatment in Electroless Silver Plating to PET Fabrics

다국어 초록 (Multilingual Abstract)

This study's purpose is to propose the basic data for development of high quality electromagnetic wave shielding fabrics in electroless silver plating. Silver nitrate is used in polyester fabric as an electromagnetic wave shielding material. The alkaline treatment and catalyst treatment are affected to durability of silver membrane in electroless silver plating. Therefore we confirmed add on and thickness of silver membrane, surface morphology and electromagnetic wave shielding effectiveness to etched degree and catalyst concentration of PET fabric. Surface morphology and wash-ability are measured using SEM. The electromagnetic wave shielding effectiveness of polyester fabrics, by electroless silver plating, is measured by using an RF Impedance analyzer. The results are as follows: The optimum weight loss by alkaline treatment of polyester fabrics is about 20%. As the concentration of $SnCl_2$ and $AgNO_3$ increases, add on and thickness of silver, electromagnetic wave shielding effectiveness increased. The optimum concentration of $SnCl_2$ and $AgNO_3$ in the catalyst reaction, is 5.0 g/l and 0.5 g/l, respectively.
