Abstract

An attempt has been made to develop a cement paint composites containing MWCNT, fly ash & ferrite encapsulated glass fibers for absorbing electromagnetic interference (EMI) pollution. The ferrite particles were encapsulated onto glass fibers by in situ polymerization method. However fly ash has been added in controlled amount to the composite in order to perform a dual function, first as dielectric filler and second to reduce solid waste generated from the thermal power plants. These composites have been used to evaluate shielding effectiveness in X b and (8.2-12.4 GHz). The results have shown that this composite can provide an effective absorption dominated shielding effectiveness of 66 dB in X band (8.2-12.4 GHz) with the incorporation of 12 wt% loading of MWCNT along with fly ash and ferrite encapsulated glass fibers in the cement paint matrix. Moreover, the cement paint composites were also tested for surface morphology, hardness, electrical conductivity and structural analysis using TEM, shore hardness test, electrical conductivity and XRD technique, respectively.
