The incorporation of carbonaceous nanofillers into polymers can result in significant materials with improved physicochemical properties and novel composite functionalities. In this study, we have fabricated antibacterial, lightweight, transparent, and flexible graphene oxide (GO) reinforced polycarbonate thin films by a facile and low-cost methodology. Solution blending is employed to get a homogeneous mixture of PC-GO composites at various loading of GO, and the thin films are prepared by dry-wet phase inversion technique. Thermal studies and micrographs of the films revealed the incorporation of GO in PC matrix. Microstructure of the thin films showed the homogeneous dispersion of GO at micro- and nanoscales; however, at higher loading of GO (0.7%), significant agglomeration is observed. More importantly, PC-GO composite films exhibited excellent antibacterial activities against E. coli and S. aureus, owing to the antibacterial nature of GO nanoparticles.

WO3-NiO thin films have been prepared using WO3 and NiO, deposited on ITO conductive glass by the sol-gel spin coating technique, which has the advantages of simple operation, low cost and high volume production. The composition, surface morphology and electrochemical properties of the obtained films were carried out using X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and electrochemical workstation. The experimental results show that after 450 °C calcination, it makes the structure of WO3/NiO obtained by sol-gel method from amorphous into crystalline. Finally, compared with the different films fabricated by different processes, the composite films of WO3 calcined at 450 °C and NiO can achieve the best electrochemical performance.
