Abstract

Incorporating metaloxide nanoparticles such as nanoalumina and nanosilica into polymer coatings to enhance mechanical durability is widely utilized in the current antiscratch and mar technologies In this article a quantitative study of the effect of a nanoalumina additive on the surface mechanical properties and scratch behavior of a twopart polyurethane coating is reported An instrumented indenter with a conical diamond tip is used to measure surface mechanical properties modulus and hardness and to perform scratch tests over a wide range of scratch loads The scratch behavior in terms of the onset of elastic–plastic transition and scratch morphology were characterized by laser scanning confocal microscopy The scratch results were correlated to the surface mechanical properties and relevant bulk material properties to understand the overall scratch behavior of the coatings The results show that the scratch behavior of the coatings depends strongly on the concentration of nanoalumina
