Influence of nanoroughness on friction coefficient and interfacial scission of amorphous glassy polymer.
Résumé
Decreasing the friction coefficient of biomedical artificial joints is of huge interest to improve their longevity. Friction coefficient is the result of three contributions: surface mechanical properties, surface topography and rheology of the biolubrication layer. This fundamental work is upstream to friction studies on biocontacts and focuses on nano-roughness effect on glassy polymer surfaces. It will extend to semi-crystalline polymers prior to biolubrication studies.
