As a filler, carboxylic acid-functionalized graphitic nanoplatelets (COOH-GN) are applied to enhance the mechanical properties and thermal stability of poly(vinyl alcohol) (PVA) and the COOH-GN/PVA_X nanocomposites are prepared through the solution mixing method into water. The COOH-GN/PVA_X nanocomposites display remarkable mechanical properties and thermal stability to compare with the pure PVA because the excellent distribution of the COOH-GN into the PVA matrix as well as strong interfacial adhesion and hydrogen bonds between PVA and COOH-GN. The COOH-GN/PVA_2 nanocomposite shows the superlative mechanical and thermal properties. So, this study shows that the graphitic nanoplatelets (GnPs) are controlled with the functional groups as well as have the excellent properties and cost-effectiveness. In result, the GnPs will be used as a reinforcing filler for hydrophobic as well as hydrophilic polymers.
