Microfriction studies of filled PPS/PTFE‐composite blends

The lateral force mode of atomic force microscopy (AFM) was applied to conduct friction tests on a filled PTFE/PPS‐composite blend. This method distinguishes between the individual phases of the blend, i.e. carbon fibers, PPS‐particles, PTFE‐matrix and graphite flakes. The relative frictional behaviours of the different filler types were compared and the law of microfriction was discussed.
