Abstract: Physical and mechanical properties and friction and wear characteristics of several polymers are reviewed in this article. Development history and situation are presented in detail. Preparation methods of polymer matrix lubricating materials have following measures: matrix mechanical properties are improved by blending polymer with polymers, fibres and whiskers; friction performances are improved by adding solid self-lubricating additives; and surface modifications are achieved by electron-radiation, plasma spraying and ion implantation. So the integrative properties of polymer matrix are improved effectively. Polymer matrix self-lubricating materials can be used instead of many traditional metal materials and become a new kind of friction and wear materials.

Key words: polymer, composite material, self-lubricating material, friction, wear
