摘要： The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.

摘要： Compositions for forming an improved vapor mitigation barrier are contemplated, such compositions being formed as an aqueous mixture of an asphalt component and a latex component, with the latex component including a chemically resistant latex, the chemically resistant latex being an acrylonitrile butadiene copolymer, an elastomeric fluoropolymer, or both. Such compositions, when cured and formed into a vapor mitigation barrier, may be seen to substantially mitigate diffusion of chlorinated hydrocarbons across the barriers. Also contemplated are methods for forming such vapor mitigation barriers, as well as vapor mitigation barrier products formed via the application of such compositions to various substrates.

摘要： A method for producing a rubber composition include a mixing step, a drying step, and a dispersion step. In the mixing step, an aqueous solution that includes at least one of oxycellulose fibers and cellulose nanofibers is mixed with rubber latex to obtain a first mixture. In the drying step, the first mixture is dried to obtain a second mixture. In the dispersion step, the second mixture is tight-milled using an open roll to obtain a rubber composition. The rubber composition does not include an aggregate that includes at least one of the oxycellulose fibers and the cellulose nanofibers, and has a diameter of 0.1 mm or more.
