Abstract

A quantitative method, using temperature controlled FFM and 'friction histograms,' has been developed to determine the frictional (dissipative) character of polymer surfaces. This method allows to correlate frictional response in films of PMMA, PET, and PS with their known α and/or β relaxation mechanisms. The rate dependence of the hindered rotation of the -COOCH3 group in PMMA is consistent with Arrhenius time-temperature behavior allowing calculation of an activation energy.
