▎ 摘　　要

The electrical conductivity of cotton fabrics is enhanced by coating with graphene in aqueous phase by a suitable process. Two different types of fabrics viz. woven and knitted structures of same GSM are used as substrate. The fabrics are dipped in dispersed graphene oxide (GO) solution and then GO-enriched fabric samples are subjected to a reduction process for in-situ conversion of the added GO to electro-conductive graphene. The concentration of GO solution and number of dipping cycles influence the graphene add-on and electrical resistivity of the fabrics. The change in surface resistivity, thickness, air permeability, porosity and water vapour permeability of the fabrics after the treatment has been evaluated. Comparisons have been made between the woven and knitted fabrics for all these properties to understand the effect of fabric structure.
