Scanning force microscopy (SFM) of topography, frictional force, and stiffness on thin gelatin films reveals an entire spectrum of tribological behavior. Two distinct phases of gelatin whose characteristics relate to the degree of crystallinity are illustrated here. Dissimilar regimes of velocity- and load-dependent friction and wear on each phase indicate glossy, rubbery, or melt behavior. Energy transferred to the film in the vicinity of the sliding SFM microaspertiy modifies film response of fundamental importance.
