Study the Effect of Bi-Layers on the Friction and Impact Resistance of PMMA/Nano-composite Hard Coatings

الوصف الكامل (Full Abstract)

A comparison work of mechanical and surface behavior of one hard coating layer and bi- layers (soft /hard layer) precipitation on poly (methyl methacrylate) substrates was studied.TiO2 was treated with appropriate coupling agent typically 3-aminopropyltrimethoxysillane (APTMS) to enhance it’s compatibility and dispersibility with polymer matrix. TiO2/ PMMA nanocomposite was chosen as a upper layer for double layers coatings and polysilicon rubber as a soft base sublayer was presented with thickness 200 ?m to show impact of a soft subbase layer on the mechanical and surface properties. The results showed that the existence of soft base layer caused decreases the coefficient of friction and enhance the impact resistance for bilayer as a compare monolayer coating.
