▎ 摘　　要

NOVELTY - Producing a composite polymeric article, comprises providing many graphene nanoplatelets; providing many silica nanofibers, where the silica nanofibers have a mean cross sectional diameter of not more than 100 nm; providing a polymeric material; and distributing the silica nanofibers and the graphene nanoplatelets within the polymeric material to achieve a composite article. USE - The method is useful for producing the composite polymeric article, where the article comprises a tire or its elements, a mechanical belt or its elements, a bumper or its elements, a shoe sole or its elements, a damper or its elements or a shock mount or its elements (claimed). ADVANTAGE - The method: utilizes the graphene nanoplatelets and the silica nanofibers that provide the tire having improvements in the rolling resistance and wear resistance of tires for breakthrough fuel savings without compromising its viscoelastic properties (i.e. traction); provides reduction in hysteric losses and provides uniform temperature distribution in a composite polymeric article; utilizes the graphene nanoplatelets that exhibits high Young's modulus, high tensile strength and high thermal conductivity; and utilizes the silica nanofibers that are crosslinked to the rubber matrix to form robust flexible interfaces that provide a reinforcement network with extraordinary mechanical integrity and wear resistance and exhibits high flexibility and high tensile strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an additive for a polymeric article comprising the graphene nanoplatelets, and the silica nanofibers, where the silica nanofibers have a mean cross sectional diameter of not more than 100 nm; and (2) a composite polymeric article comprising the graphene nanoplatelets, the silica nanofibers, and the polymeric matrix, where the graphene nanoplatelets and silica nanofibers are distributed within the matrix.
