▎ 摘 要
NOVELTY - Preparation of graphene, graphene oxide, or reduced graphene oxide of one or more layers or a polymeric material comprising graphene, graphene oxide or reduced graphene oxide of one or more layers comprising an in-situ exfoliation of graphite, graphite oxide or reduced graphite oxide involves kneading the graphite, graphite oxide or reduced graphite oxide in a polymer or a polymer mixture at temperature below the melting point of the polymer or the polymer mixture, to produce a thermoplastic and/or elastomeric polymer or polymer mixture comprising graphene, graphene oxide or reduced graphene oxide of one or more layers. The polymer is a thermoplastic and/or elastomeric polymer. USE - Preparation of polymeric materials comprising graphene, graphene oxide, and reduced graphene oxide of layer(s) used for conferring of electrical conductivity, thermal conductivity, improved thermal stability, mechanical reinforcement, wear resistance, impact resistance, improvement of the barrier to the passage of gases and liquids (all claimed). ADVANTAGE - The method produces polymeric materials comprising graphene, graphene oxide, or reduced graphene oxide of layer(s) having excellent electrical conductivity, thermal conductivity, improved thermal stability, mechanical reinforcement, wear resistance, impact resistance, and improvement of the barrier. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) polymeric material; and (2) conferring of electrical conductivity, thermal conductivity, improved thermal stability, mechanical reinforcement, wear resistance, impact resistance, improvement of the barrier to the passage of gases or liquids, and fire resistance properties to a polymeric material, which involves preparing the polymeric material.
