Modification of poly-ether-ether-ketone (PEEK) to adapt to the biological properties of materials is currently the key point in the research of medical materials. The tribological properties and biocompatibility of the PEEK composites modified by carbon fiber (CF), potassium titanate whisker(PTW) and nano-particles were discussed in this paper. The results show the modified PEEK composites by a certain length to diameter ratio of CF show the best using effect in vivo experiments in good blood compatibility, which is suitable for orthopaedic implant materials. A large number of experiments show that the PEEK composites would be modified with a certain ratio of CF (about 30%wt.), whisker (about 15%wt.) and HA (about 5%wt.) particle with better biological tribological properties, more important value in medical research.

改性聚醚醚酮复合材料的生物摩擦学性能

聚醚醚酮（PEEK）的改性以适应材料的生物学特性是目前医学材料研究的重点。本文讨论了碳纤维（CF），钛酸钾晶须（PTW）和纳米粒子改性的PEEK复合材料的摩擦学性能和生物相容性。结果表明，以一定的长径比CF改性的PEEK复合材料在体内实验中具有最佳的血液相容性，具有最佳的使用效果，适用于整形外科植入材料。大量实验表明，PEEK复合材料将以一定比例的CF（约30％wt。），晶须（约15％wt。）和HA（约5％wt。）颗粒进行改性，具有更好的生物摩擦学性能。 ，在医学研究中更重要的价值。
