制备出稳定分散的乙二胺缩水杨醛Schiff碱铜（Ⅱ）配合物微纳米粉体,并用扫描电镜和红外光谱鉴定其结构和粒径。在25（体积分数）小牛血清去离子水溶液边界润滑条件下,以5（质量分数）微纳米乙二胺缩水杨醛Schiff碱铜（Ⅱ）配合物作为添加剂改性UHMWPE,与Ti6Al4V配对进行往复摩擦磨损试验,并与其微米级粉体改性UHMWPE的摩擦学性能进行对比。结果表明,在改性添加剂质量分数为5时,对于减少改性UHMWPE自身和对偶件Ti6Al4V的磨损和降低摩擦副的摩擦,乙二胺缩水杨醛Schiff碱铜（Ⅱ）配合物微纳米粉体比其微米级粉体更加有效。 A kind of stable dispersed micro-nano-powder of copper（Ⅱ） complex with ethlenediamion-N,N＇-bis（salicylidene） was prepared,and its structure and partial size were identified by IR and SEM.Reciprocating friction and wear behaviors of UHMWPE modified with 5%（mass fraction） of the micro-nano-powder of copper（Ⅱ） complex with ethlenediamion-N,N＇-bis（salicylidene） was investigated and compared with the one with micro size by pairing up with Ti6Al4V under the condition of boundary lubrication with 25%（volume fration） calf serum deionized water solution.Results show that the micro-nano-powder of copper（Ⅱ） complex with ethlenediamion-N,N＇-bis（salicylidene） is more effective for improving anti-wear property of the modified UHMWPE itself and the counterpart（Ti6Al4V） and for reducing friction of modified UHMWPE/Ti6Al4V than the one with micro size when additive amount is 5%（mass fraction）.
