Aksay and Richard A. Register and Douglas H. Adamson}, title = {Electrically conductive polymer nanocomposites containing functional graphene}, abstract = { A polymer compn. comprises a polymer matrix comprising an elastomer, and a functional graphene which displays no signature of graphite and/or graphite oxide, as detd. by X-ray diffraction. The functional graphene-contg. polymer compns. have excellent strength, toughness, thermal stability, elec. cond., and can be used for prodn. of gas-barrier materials. Thus, films (200-400 μm) made of a silicone rubber RTV 615 compn. contg. 5\% of functional graphene nanoparticles had a Young{\textquoteright}s modulus 12.18 and a tensile strength 6.52 times higher than the resp. values for neat rubber. Similar films made of a silicone rubber RTV 615 compn. contg. 5\% of clay nanoparticles had a Young{\textquoteright}s modulus 1.28 and a tensile strength 2.38 times higher than the resp. values for neat rubber.
