1. An oilfield apparatus, comprising:

  • an oilfield element made of a composite comprising;

    a matrix material; and

    a plurality of functionalized graphene sheets dispersed in the matrix material, wherein the oilfield apparatus is a downhole tool,wherein the plurality of functionalized graphene sheets comprise single-layer sheets and multi-layer sheets having a surface area per unit weight of at least 300 m2/g, andwherein the plurality of functionalized graphene sheets are functionalized with polymers with a polydispersity index such that the polymer hinders folding of the plurality of functionalized graphene sheets.
