Polymeric Lubricants

Poly(tetrafluoroethylene) polymers have found a limited use as lubricants. They arse used for materials that should exhibit a high abrasion resistance.

As temperature increases, the layer expands and the orientation of endbeads smears. This is shown in Figure 1.46. The observed expansion of layer thickness is attributed mainly to the temperature dependence of the intermolecular interaction and excluded volume effect not due to bond stretching. Temperature dependence, which is pertinent to the annealing process of thin polymeric lubricant films, has been carefully examined by Hsia et al. [171]. 

A recent development in solid bearing lubricants is microporous polymeric lubricants, MPL, where a polymer containing a continuous microporous network has oil contained within the pores, which may include appropriate additives [56], The oil content in the polymer can be more than 50% by weight and the microporous polymer acts as a sponge, releasing and absorbing oil when necessary.
