摘要：The present invention pertains to a process for producing a compositioncomprising graphene and at least one polymer, and especially for producing a graphene-

filled polymer nanocomposite. Specifically, the present invention resides in a process formanufacturing a composition comprising graphene and at least one polymer, the processcomprising the steps of: (i) providing an aqueous suspension of graphene [dispersion (G)];(ii) mixing the dispersion (G) with an aqueous polymer latex to obtain a liquid mixture[mixture (M)]; and (iii) co-coagulating the mixture (M) to obtain said composition. Thegraphene-filled polymer nanocomposites made by the process of the present inventionhave advantageously shown excellent barrier properties, indicating a nearly homogenousand sufficiently scattered filler distribution in the base polymer.
