Abstract

The invention relates to a macromolecule load-type palladium activated film preparation by complex coordination self-assembly technology and comprises the following procedures that: (1) noble metal palladium salt colloid solution is formed to a uniform, stable and dispersed system; (2) fabric is dipped in the prepared dispersed system for a certain time; Pd complex compound and high polymer load monomers are formed on the surface of base fabric; (3) after the temperature rises, the solubility of the colloid in the solution is reduced, dehydrated and shrunk, that is separating pulp; a metal ultrafine particle palladium load catalyst layer is achieved after deoxidization. (4) The reunite of nanometer metal palladium is limited in the high polymer; the noble metal palladium ultrafine particles are formed into the original position, thereby achieving the noble metal palladium ultrafine composite layer. The invention is simple and effective in technique; the prepared material is widely applied to anti-radar detection, military target invisibility, anti-electromagnetic interference and multiaspects.

Description

technical field [0001] The invention relates to the field of functional finishing of metallized textiles, in particular to a method for preparing a polymer-loaded palladium activated membrane with coordination self-assembly technology. Background technique [0002] As a new type of EMC material, metallized textile (also known as conductive cloth) has both the conductive and electromagnetic shielding properties of metal and the soft and breathable properties of textiles. It is widely used in the preparation of conductive gaskets, flexible cables, and conductive tapes. It has good It has excellent shielding performance and is currently an emerging shielding material with a wide range of uses. [0003] Metallization of textiles is to form a very thin metal composite layer on the surface of textile fibers by means of electroless plating or sputtering. Resin → drying", the key process is activation. The necessary condition for electroless plating is that the surface of the obje...
