Graphene-impregnated microfiber fabric

A graphene-impregnated microfiber fabric, comprising:

• a microfiber substrate comprising polymer fibers;
• graphene coating the polymer fibers;
• and
• a polymer material coating the polymer fibers and bonding the graphene to the polymer fibers.

A method of producing a graphene-impregnated microfiber fabric, the method comprising:

• providing a microfiber substrate comprising polyester fibers;
• mixing a graphene-based paste comprising graphene nanoplatelets into a polyurethane-based dispersion to create a graphene-impregnated polyurethane-based dispersion;
• forming the graphene-impregnated microfiber fabric by immersing the microfiber substrate in the graphene-impregnated polyurethane-based dispersion to coat the polyester fibers of the substrate with the graphene nanoplatelets and polyurethane;
• removing the graphene-impregnated microfiber fabric from the graphene-impregnated polyurethane-based dispersion;
• and
• drying the graphene-impregnated microfiber fabric.
