Abstract

Atomic force microscopy (AFM) has become established as a powerful and versatile tool for investigating local mechanical properties. In addition, through the AFM tip-sample interaction, it has become possible to study the effects of perturbations and modifications to the surface of soft samples, such as polymers. The accurate knowledge of their response to continuous AFM scanning could help to design new materials having desirable mechanical properties. In this paper, we present the results obtained by applying a new methodology to investigate wear properties on two different type of polymer, poly(methyl-methacrylate) and poly(L-lactic acid). These polymers have been widely employed in biomedical applications and have recently been considered as good candidates for coronary metallic stent coatings.
