摘要：

In this work, polyurethane (PU) materials containing paraffin oil are successfully prepared via an emulsion template method, which realizes the one-pot preparation of self-lubrication materials. The results show that the block copolymer surfactant (PEG(20)-PPG(70)-PEG(20), P-123) can stabilize the nonaqueous PU emulsion with the paraffin oil serving both as dispersed phase of oil in oil emulsion and as a lubricant in the materials, and hence enables the fabrication of oil incorporating PU materials accordingly. Tribological tests show that the friction coefficient of PU material with 35% paraffin oil decreases to 0.05 which account for 93.06% reduce compared to that of pure PU.
