Abstract

This chapter reviews recent advances in the modification of graphene nanosheets and fabrication of graphene nanocomposites with conjugated, saturated, and electroactive polymers. The conjugated polymers can be grafted on the graphene nanosheets mainly via amidation, ?–? stacking interaction, and 1,3-dipolar cycloaddition, while the saturated polymers can be grafted on the nanosheets by a combination of noncovalent and covalent approaches. The electroactive polymers, such as polyaniline, polypyrrole, and polythiophene, can be conjugated with graphene nanosheets via in situ oxidative polymerization, electrochemical polymerization, and the “grafting-to” approaches. The resulting graphene-based polymer nanocomposites have found applications and potential applications in solar cells, electronic memories, supercapacitors, dielectric materials, sensors, and drug delivery systems, among others. Herein, the preparation, characterization, and applications of the graphene-based polymer nanocomposites are described in detail with specific examples on application drawn from the scientific literature.
