Thermal and electric protection behaviour of Gnp's functionalized wool fabrics

Abstract

Technical textiles and functional garment assemblies can be engineered to optimize the protection against heat, flame, molten metal, static electricity, electromagnetic radiation, chemical agents, among others. The present work aims to study the use of wool-based fabrics as a fibrous substrate for thermal and electric protection by surface functionalization with Graphene Nanoplatelets (GNP’s) in polymeric-based dispersions. Wool fabrics were functionalized with 1% GNPs dispersed in chitosan and polyurethane, using impregnation and coating techniques. The results show that wool fabrics coated with polyurethane (PU) functionalized with 1% GNPs present an interesting approach regarding multiscale protection.
