Graphite oxide (GO) is a widely used precursor to make graphene and its composites. Studies have been conducted on graphene-based nanomaterials including modified graphene, graphene/semiconductor hybrids, graphene/metal nanoparticles composites, and graphene-complex oxide composites. These nanomaterials inherit the unique properties of graphene, and the addition of functional groups or the nanoparticles composites on their surfaces improves their performance. Reliable production of graphene derivatives, such as graphene oxide (GO) and reduced graphene oxide (rGO), offers a wide range of...

Titanium dioxide-Graphene oxide (TiO2-GO) composites with different concentrations of GO to TiO2 were synthesized using a colloidal blending process and evaluated for their heterogeneous photo catalytic degradation of methylene blue for removal of pollutants .Both SEM and FTIR demonstrated the presence of a carbon component in the as-prepared TiO2-GO composites. Unlike unmodified TiO2, the TiO2-GO composites showed a light-absorbance shift into the longer wavelength regions, indicating "Band-gap narrowing". A simple method of depositing titanium dioxide (TiO2) Nano particles onto Graphene...

In recent years, polymers are extensively utilized in tribological components such as cams, brakes, bearings and gears because of their self-lubrication properties, lower friction, better wear resistance, low noise and cost. Polymers are associated with some inherent deficiencies which can be altered successfully by using various special fillers there by producing polymer composites. More and more polymer composites are now being used as sliding components, which were formerly composed only of metallic materials. Polymers used for fabrication of tribological components should have excellent...
