dc.description.abstract | Graphite oxide (GO) has been synthesized from graphite by chemical oxidation method and characterized for its thermal, morphological and structural attributes by techniques such as thermogravimetric analysis (TGA), high resolution transmission electron microscopy (HRTEM), Raman, Fourier transform infrared (FTIR) spectroscopy, and powder X-ray diffraction (XRD). The as synthesized GO was used to prepare graphene coated cotton-polyester fabric by dip coating technique followed by chemical reduction. These fabrics were subjected to SEM, XRD, TGA and contact angle measurements which confirm the presence of GO coating over fabrics and its successful conversion into reduced GO (RGO) after chemical reduction. It was also observed that increase in graphene loading leads to enhancement of both electrical conductivity and mechanical properties. Interestingly, the low conductivity samples (graphene loading <2%) conforms to anti-static resistance range whereas higher graphene loading sample (>7 %) display electromagnetic interference (EMI) shielding capability with shielding effectiveness value upto -26.67 dB for a three layer shield. | en_US |
