Studying the Tribological and Mechanical Properties of the PMMA Nano Composite Coating

This work includes preparing and studying a transparency polymeric coating that has good tribological and mechanical properties.Coating enhanced with nanoparticles can absorb UV radiation while keeping transparency.Also, coating leads to lowering the friction coefficient that improves the coating's wear resistance performance for mobile and computer screen applications, also it leads to increasing the life span of car lamp covers and glass, plastic windows and coating of solar cells.The nanocomposite coating consists of Graphene oxide (GO), Graphene oxide modified (MGO).Composite coating samples with GO and MGO nanoparticles at various weight percentages (0, 0.25, 0.5, and 1 wt%) were created by employing a solution mixing process.Scanning electron microscopy (SEM) was used to evaluate the distribution of nano and fracture failure.Hardness, DSC, wear and scratch tests were done.Additionally, the relationship between tribological and mechanical behavior was studied, as well as the mechanical properties of PMMA nanocomposites coating with the nanoparticle addition.The results showed that adding GO, MGO nanoparticles enhanced the PMMA's tribological performance.It was discovered that PMMA nanocomposites coating had a lower wear and friction coefficient than pure PMMA coating.According to the microstructure data, the ultrasonic treatment significantly contributed to the nanoparticles' good dispersion and decreased agglomeration.The results of mechanical qualities, such as hardness, demonstrated a discernible improvement..
