Tribological and Rheological Investigations of MWCNT/PMMA Polymeric Composites and Hybrid Compounds

Abstract

The Nano scale self-lubricating compounds were prepared by in-situ free radical polymerization with the dispersion of MWCNT ultrasonic molecules embedded in the polymer matrix to enhance the tribological mechanical properties as well as the production of hybrid compounds to detect the tibial changes on the polymer surface, dry friction under the conditions of slip was studied, the friction coefficient was found For hybrid compounds slightly lower than the coefficient of friction of Nano composites under multiple loads and constant velocities, enhancements of Nano composites in rheological behavior were investigated and the influencing factors were determined: shear stress, shear viscosity, as well as shear rates. By using visual inspection, tracking of the behavior of compounds during extrusion was carried out and obtaining the shapes of the threads resulting from extrusion, which are usually important matters whose results depend on many industries.
