Structure and Properties of Reduced Graphene Oxide/Natural Rubber Latex Nanocomposites
Abstract:
In this work, the morphology and properties of graphene modified natural rubber (NR) was studied. Graphite oxide was chemically reduced with poly(sodium 4-styrenesulfonate) as a stabilizer, then the obtained graphene was blended with NR using latex technique. It is observed that a stable graphene suspension was fabricated by chemical reduction of graphite oxide in the presence of surfactant, while graphene was dispersed homogeneous in NR matrix as tested by WAXD and TEM. Dynamic mechanical analysis showed that storage modulus enhanced dramatically after the incorporation of graphene due to the high surface area of graphene and the exfoliated structure of graphene in NR. The electrical property and thermal conductive properties of NR/graphene nanocomposites improved significantly following the increase in graphene concentration.

Structure and Physical Properties of Alkynes
In nature, compounds containing both carbon and hydrogen are known as "hydrocarbons". Aliphatic hydrocarbons are compounds whose molecules contain saturated single bonds (i.e., alkanes) or unsaturated double or triple bonds. Alkenes contain carbon–carbon double bonds and have a structural formula CnH2n. Unsaturated hydrocarbons containing carbon–carbon triple bonds are called "alkynes" and are structurally represented by the formula CnH2n-2.
