Abstract

Graphite nanoplatelets (GnP) were prepared by ultrasonication of thermally expanded graphite intercalated compound. In-situ oxidative polymerization was done to prepare GnP (1 wt%, 3 wt% and 5 wt%) filled polyaniline–gum arabic (GnP/PANI–GA) nanocomposites. These nanocomposites were further coated on the surface of the cotton fabric through the pad-dry-cure process. The characterization of the prepared nanocomposites and their coating was done by Fourier transform infrared spectroscopy and field emission scanning electron microscopy along with energy dispersive spectroscopy. Also, the mechanical, ultraviolet shielding and flame retarding properties of these coated fabrics were analysed as per ASTM D 5035, AATCC TM 183 and FMV SS 302 standards. 3 wt% GnP/PANI–GA nanocomposite coated fabric showed enriched tensile strength of (145 N) in weft direction, ultraviolet protection factor of 58, burn time of 173 s and limiting oxygen index of 26.10% as compared to 116 N, 5, 88 s and 18.3% respectively for the pure cotton fabric. Overall, the 3 wt% GnP/PANI–GA nanocomposite was evaluated as the optimum concentration because of the uniform dispersion of GnP in PANI/GA nanocomposite.
