The Preparation of Ni-Co-Fe/PU Magnetic Composite Membrane

Abstract

On the base of electroless plating on fabric, the Ni-Co-Fe was plated on the PU membrane of coated polyamide fabric and the respiratory electromagnetic shielding fabric was developed. The functionality and wear-ability of electromagnetic shielding fabric was tested and analyzed. The results showed that it has good electrical conductivity, water vapor permeability, electromagnetic shielding performance and durability and so on. With the weight increasing rate goes up, the shielding effectiveness, vapor permeability and electrical conductivity increases obviously, then prone to slow increment. The plated layer on fabric has an adverse effect on the wear performance and on the premise of meeting respiratory and electromagnetic shielding performance, the thickness of plated layer should be decreased to the least extend.
