Experimental Study on Synthesized Graphite Nano Particles Based PVA Nanocomposites

The present work aims to develop Graphite Nano Particles (GNP’s) based Poly Vinyl Alcohol (PVA) nano composites. Cold water soluble PVA is used in the present study which is blended fractionally with synthesized graphite nanoparticles in the ratio of 0.25, 05, 0.75 and 1% by weight by open mold method followed by autoclave curing to ensure proper curing of prepared samples. The synthesized graphite nanoparticles were subjected to UV–vis spectroscopy analysis, where in the highest peak was observed at 255 nm. Major contribution of this present investigation deals with the computational studies of composition elements to study various factors such as nuclear structure using the Density Functional theory (DFT). Stability analysis of each molecule is performed separately using the UB3LYP calculation method with the help of 6-31G basis set function. Addition to this Nuclear magnetic resonance (NMR) study and vibration analysis were performed using GAUSSIAN 9, Gauge-Independent Atomic Orbital (GIAO) method was used for NMR determination.
