Nanocompuestos poliméricos a partir de grafeno

Abstract

Graphene sheets have recently attracted considerable attention as a viable and inexpensive filler substitute for carbon nanotubes in nanocomposites, given the predicted excellent in-plane mechanical, structural, thermal, and electrical properties of graphite. Recent studies have shown that individual graphene sheets have extraordinary electronic transport properties. Exfoliation of graphite oxide represents an attractive route to functionalized graphene as versatile 20 carbon nanomaterials and components of a variety of polymer nanocomposites. This review presents a general approach for preparing polymer/graphene composites via complete exfoliation of graphite and molecular-level ispersion of individual, chemically modified graphene sheets within pOlymer hosts.
