To better elucidate the effect of fibers in the polymer – filler interfacial boundary on the properties of PCM, the supramolecular structure of the composite was studied in more detail. As is known, one of the factors for increasing the wear resistance of PTFE with the addition of almost any type of filler is the transformation of the polymer matrix from ribbon to spherulite.
