Electrically conductive materials based on cotton have important implications for wearable electronics.

Abstract
Electrically conductive materials based on cotton have important implications for wearable electronics. We have developed flexible and conductive cotton fabrics (similar to 10 Omega/sq) by impregnation with graphene and thermoplastic polyurethane-based dispersions. Nanocomposite fabrics,display remarkable resilience against weight-pressed severe folding as well as laundry cycles. Folding induced inicrocracks can be, healed :easily by hot-pressing, restoring initial electrical conductivity. Impregnated cotton fabric conductors demonstrate better mechanical properties compared to pure cotton and thermoplastic polyurethane maintaining-breathability.
