Friction and Wear Behavior of the Hybrid PTFE/Cotton Fabric Composites Filled With TiO2 Nanoparticles and Modified TiO2 Nanoparticles.

The article discusses polymer engineering research wherein titanium dioxide (TiO₂) was chemically grafted by covalently introducing glycidoxy-propyltrimethoxy silicane followed by polyoxymethylene to overcome disadvantages generated by the agglomeration of nanoparticles. Both modified and unmodified TiO₂ nanoparticles were introduced into hybrid polytetrafluoroethylene (PTFE)/cotton fabric composites. Fabric composites filled with grafted nanoparticles showed a lower wear rate due to the disintegration of agglomeration and improved interfacial adhesion between the filler/matrix.
