High mechanical strength coated conductive flexible cotton fabric with electrical and electromagnetic interference (EMI) shielding properties has been developed by low cost and facile one-pot fabrication technique. Herein, polyvinyl alcohol (PVA) and natural rubber latex (NRL) have been judicially amalgamated with specialty conducting black. The polymer blends were not only physically mixed but also covalently interwoven by means of inter-penetrating polymeric network (IPN) approach. The morphological study combined with electron microscopy and 3D micro-computed tomography reveals uniform and flexible conductive network formation. The coated fabric was tested under rigorous environmental and practical factors/stresses (e.g., prolonged sunlight exposure, flexibility under liquid nitrogen, abrasion, water durability and detergent action) which provide information regarding the sustainability of the fabric …
