✦ Synopsis

The optical micrographs show thermoplastic polyimide surfaces after sliding at different temperatures. The tribological mechanisms of polymers can be evaluated with Raman spectroscopy, showing three sliding regimes with hydrolysis inducing high friction and low wear, imidisation inducing low friction and high wear and finally melting inducing high friction and high wear. Further details can be found in the article by P. Samyn,* G. Schoukens, F. Verpoort, J. Van Craenenbroeck, and P. De Baets on page 523. Contents Review Trends in tribological properties for polyimides are reviewed in relation to known mechanical effects. Tribophysical analysis of the worn polymer surfaces by Raman spectroscopy gives new insights in chemical modifications at the sliding surface and hydrolysis or imidisation reactions are well-related to transitions in sliding performance.
