Lubrication of polymers

They are widely used as surfactants particularly in emulsification and polyurethane foam stabilization. They orient at air/liquid and solid/liquid boundaries in a manner suitable for lubrication of polymer interfaces.

It has been noted that many polymeric systems have the capacity to induce what is called self lubrication. As a consequence it has not been a major focus of research activity, compared to metallic and ceramic systems, to study the lubrication of polymers per se, but more often to consider the infiuence of environmental sensitivity. For convenience the two are dealt with together here. We may also note that polymers are often included into polar and apolar solvents to modify the rheological behaviour as is conunon practice in the formulation of viscosity improvers and the development of drag reducing agents. These processes may have implications in rationalisation of environmental sensitivity. 

Many of the special features of the boug ary lubrication of polymers are introduced in a companion paper and will not be repeated in detail. It is now evident that the fluid should... 

It is generally recognised that effective lubrication of polymers using liquids is very difficult to achieve except at high sliding velocities when fluid lubrication can operate.
