Abstract
Nanocomposite films of PVA (polyvinyl alcohol) with GF(graphene flakes), GO (graphene oxide) and G(Graphite) as nanofillers have been synthesized. Nanocomposites were prepared to contain various weight amounts of nanofiller (0.3, 1, 1.5, 2 and 3%) within PVA matrix. The film is cast on a clean glass plate through the solution casting method and dried in the oven. Here a report of a simple and practical approach to synthesizing graphene-reinforced poly (vinyl alcohol) (PVA) composite films by incorporating other filler into PVA aqueous solution. Further, the investigation of thermal properties was used using thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). Thermal stability shows the best stability with the nanofillers content of 1% for G, GO and GF. Nanocomposites with an additional of 1% GF gives the highest thermal stability compared to 1% of G and GO.
