摘　　要：在聚醚醚酮 (PEEK)玻璃化转变温度以下 ,用外动式高能旋转球磨机使PEEK和二氧化锆 (ZrO2 )混合物反复变形、断裂和结合 ,并形成新的相 ,即形成PEEK/ZrO2固体合金 .通过扫描电镜 (SEM)、差示扫描量热仪 (DSC)、红外光谱 (FT IR)和动态热力学分析装置 (DMTA)对PEEK/ZrO2 =1/2和 2 /1固体合金的结构及性能进行研究 ;并与纯PEEK对比 ,探讨PEEK与ZrO2 形成固体合金的可能性 ;讨论固体合金化工艺对PEEK/ZrO2 固体合金性能的影响 ,分析PEEK/ZrO2The compound of polyetheretherketon (PEEK)/zirconium dioxide (ZrO2) was distorted, fractured, and welded together, and the new phase was formed through the diffusion of all kinds of atoms of components, in high energy rotating ball mill at temperatures below the glass transition temperature of PEEK, that is to say, the solid alloy of PEEK/ZrO2 was formed. The structure and physical properties of the polymeric alloy, whose formulas were 1/2 and 2/1, were investigated, by means of SEM, DSC, IR and DMTA. By contrast with pure PEEK, the possibility of mechanical alloying of PEEK and ZrO2 was explored. The effect of mechanical alloyjing process on the properties of PEEK/ZrO2 solid alloy was discussed, and the mechanism of mechanical alloying was analyzed.
