    摘要: Disclosed is a reinforced biodegradable polymer nanocomposite. The reinforced biodegradable polymer nanocomposite comprises a polymer matrix and functionalised graphene nanoplatelets or graphene-like material dispersed in the polymer matrix. The graphene nanoplatelets or graphene-like material are functionalized with functional groups in a manner that planar structure of the graphene nanoplatelets or graphene-like material is retained. Disclosed further is a method of manufacturing the aforementioned reinforced biodegradable polymer nanocomposite. The method comprises functionalizing graphene nanoplatelets or graphene-like material with functional groups in a manner that planar structure of the graphene nanoplatelets or graphene-like material is retained; and dispersing functionalized graphene nanoplatelets or graphene-like material in the polymer matrix to form the reinforced biodegradable polymer nanocomposite.

    摘要: This rubber composition comprises a rubber wet master batch which uses a rubber latex solution and a carbon black (A)-containing slurry as raw materials, rubber, and carbon black (B), wherein the amount of the carbon black (A) in the rubber wet master batch is 1 to 35 parts by weight with respect to 100 parts by weight of the rubber component in the rubber wet master batch, and the total amount of the carbon black (A) and (B) in the rubber composition is 50 parts by weight or more with respect to 100 parts by weight of the total rubber component in the rubber composition. Accordingly, the present invention can provide: a rubber composition from which vulcanized rubber having excellent low heat generating properties and wear resistance can be obtained; and a method for producing the rubber composition.
