Abstract

Graphene nanoribbons (GNRs) synthesis methods are discussed along with its characterization. GNRs are modified with a functional group to tailor the properties of GNRs. The reinforcement of GNRs in polymer matrix nanocomposites has influenced the mechanical, electrical, rheological, and thermal properties. The GNRs are superior to multiwalled carbon nanotubes (MWNTs) as a filler material in polymer nanocomposites established through experimental observations. Further, the modification of GNRs covalently and non-covalently improves the dispersion of GNRs in the polymer matrix and improves the properties of nanocomposites significantly. The GNRs filled polymer nanocomposites show the applications like corrosion protection of metal, Joule heating to evaporate moisture, EMI shielding for protecting devices, a sensor for gas sensing, and oil separation by processing hydrophobic polymer nanocomposites foam.
