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 (PEG20‐PPG70‐PEG20, 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.

含油自润滑聚氨酯材料的单锅合成及其摩擦学性能
通过乳液模板法成功制备了含石蜡油的聚氨酯（PU）材料，实现了单锅自润滑材料的制备。结果表明，嵌段共聚物表面活性剂（PEG 20 -PPG 70 -PEG 20，P-123）可以与既作为在油包水乳液的油分散相和作为材料的润滑剂服务于石蜡油稳定非水PU乳液，因此，能够相应地制造掺有PU材料的油。摩擦学测试表明，含35％石蜡油的PU材料的摩擦系数降低至0.05，与纯PU相比降低了93.06％。
