Evaluation of structural and optical properties of graphene oxide-polyvinyl alcohol thin film and its potential for pesticide detection using an optical method

In the present work, graphene oxide (GO)–polyvinyl alcohol (PVA) composites thin film has been successfully synthesized and prepared by spin coating techniques. Then, the properties and morphology of the samples were characterized using Fourier transform infrared spectroscopy (FTIR), ultraviolet-vis...
