THE EFFECT OF PLASTICIZATION ON THE INTERFACIAL FRICTION OF POLYPHENYLENE OXIDE
Polymers show some very interesting frictional properties and are an excellent subject for friction research. Many polymers are readily coated onto substrates as a smooth thin film, and the physical properties of the polymer can be adjusted by processing conditions. Hence, the surface energy, surface roughness and film thickness of the polymer can be kept relatively constant whilst the crosslink density, degree of crystallisation or fraction of plasticizer can be altered in a systematic manner. This allows one to study the role of different polymer properties on the observed friction process. As they can be made very smooth they can show interfacial friction which applies to situations where the apparent contact area is comparable to the real contact area and where the normal load is much less than that required for the polymer to yield and plastically deform.
