Abstract

Cotton and polyester fabrics were coated with a hyperbranched polyurethane (HBPU) solution including multi-walled carbon nanotubes (MWNTs) using a spraying method. The MWNT-coated fabrics showed good water repelling properties at $70^{\circ}C$ and room temperature due to presence of well dispersed MWNTs on the fabric surface. The electrical heating effect of the MWNT-coated fabrics was demonstrated when a DC voltage of 10-30 V was applied to the fabrics, which was dependent on the electrical conductivity of the MWNT/HBPU composites. The MWNT coating on the fabric surface by spraying may be a good method for achieving electrical heating and water repellence.
