Structural and optical properties of PVDF/GO nanocomposites: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0



Graphene oxide (GO) was ready by means of the modified Hummar’s technique. The polymer nanocomposites (PNC) composed of polyvinylidene fluoride (PVDF) and GO, with totally different wt% of GO had been ready, following the answer casting technique within the type of skinny movies. The micro/nano-structural options and the optical properties of the PNC have been studied. The formation of GO was confirmed by means of FTIR and Raman spectra evaluation. The microstructure, homogeneity, extent of agglomeration and the fundamental composition of the PNC had been discovered by means of the FESEM, power dispersive evaluation of X-rays and the fundamental dot mapping, confirming glorious homogeneity of the PNC movies. The optical properties like absorbance, refractive index, the extinction co-efficient and the dispersion conduct had been investigated with the assistance of UV-visible spectrophotometer and spectroscopic ellipsometer respectively. The outcomes reveal a rise in absorbance with the rise of weight % of GO within the PNC, attributed to greater electrical conductivity and floor space of GO. The optical parameters (e.g., refractive index, extinction coefficient, and so on.) within the seen area present massive variation as a perform of weight % of GO resulting from PVDF/GO interplay and optimized properties was discovered to be for the 5% PNC, making it appropriate for varied optical purposes.
