1 COF measurement demonstration. In modern theory of friction, 90% of the total friction is believed to come from interatomic adhesion between two surfaces . If the interatomic adhesion is weakened, the friction force could be reduced. If water, the most abundant fluid in the body, easily wets the polymer surface and creates a thin layer between two surfaces to eliminate solid/solid contact, the friction force could be significantly reduced. Therefore, a general approach of friction reduction is to increase the surface hydrophilicity of polyurethane by coating or by surface chemical modification [9–22].
FTIR showed almost identical spectra on both polyurethanes. XPS did show different spectra on two lots of polyurethanes but failed to reveal the identity of the chemicals on the surface. 15). 16).
