A method of electroless silver plating on the surface of PA6 fiber

Abstract

A layer of silver was deposited on the surface of PA6 fiber fabric by electroless plating method to prepare silver/PA6 conductive fabric. The surface morphology and structure of the coating were analyzed by SEM and EDS. Electroless plating process conditions: 11 g/L silver nitrate, ammonia and sodium hydroxide appropriate preparation into 1.1% silver ammonia solution. Ingredients of reducing agent: glucose 10 g/L, tartaric acid 2 g/L, ethanol 100 ml/L, pH 11-13 was adjusted by adding 10 g/L sodium hydroxide solution, temperature 20-30 °C, reaction time 3min. The resistance of the preparation of silver/PA6 fabric is less than 1 Ω/cm, elemental silver content is 100%, the conductivity is excellent, and the electromagnetic radiation resistance is excellent.
