NOVELTY - A thermally conductive modified natural or synthetic leather material for a lining of product e.g., passenger compartment of vehicle, comprises thermally conductive agent including graphene particles, crust substrate impregnated with thermally conductive agent at sufficient concentration to provide thermal conductivity in modified material, and greater than or equal to 1 layers applied on the substrate and comprising graphene particles. The modified material having a thermal decay of greater than or equal to 29% starting from 70 degrees C at ambient temperature of 21 degrees C in less than or equal to 20 s. USE - A thermally conductive modified natural or synthetic leather material for a lining of product, e.g., passenger compartment of vehicle. ADVANTAGE - The leather has increased performances, increased thermal dissipation by impregnating and increased temperature decay after exposure to heat source, and has better feeling to user when portion of leather product is exposed for a long time to a heat source. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for modifying a natural or synthetic leather material for providing a thermal conductivity in modified material which involves impregnating a crust substrate with an aqueous bath comprising not greater than 6 wt.% graphene particles with respect to the substrate as a thermally conductive agent; applying on one substrate greater than or equal to 1 layers comprising graphene particles.
