A PROCESS FOR THE PREPARATION OF A NOVEL CONDUCTING FIBROUS COMPOSITE FOR ELECTROMAGNETIC INTERFERENCE (EMI) SHIELDING APPLICATIONS

摘要

A process for the preparation of a novel conducting fibrous composite for electromagnetic interference (EMI) shielding applications by loading the clean fibrous matrix, with a hetero aromatic monomer, capable of forming into conjugated polymeric structure in an amount in the range of 1-50% w/w in an organic solvent used is an amount of of 2-10 times w/w, optionally adding emulsifier in the range of 0.1 to 1% w/w either in vacuum or ultrasonics by known methods optionally in presence of monomer penetrating accessory, reacting the monomer loaded fibrous matrix, with any oxidising agent in the range of 0.5 to 8 moles per mole of monomer, washing the polymeric matrix, with water followed by drying by known method to get the conducting polymeric fibrous composite.
