The application prospect of material will be more wide.The modulus of elasticity of medical polyetheretherketonematerials materials (PEEK) is matched the most with body bone tissue,
Bone information and osteanabrosis that stress-shielding effect is caused are effectively reduced, and fatigue resistance is protruded, and is suitable for medical treatment implantation dress
Put and be chronically implanted (Biomaterials2007,28:4845-4869.).However, PEEK bioactivity is poor, after implantation human body not
Easily it is bonded with body bone tissue, while PEEK is without obvious antibiotic property, easy breed bacteria, limits it as implant material after implantation
Material is chronically implanted.How to improve PEEK Integrated implants and antibiotic property has become study hotspot.Polyetheretherketonematerials materials are entered at present
The main method that row surface is modified is chemical graft process, and this method is modified depth as shallow, and effect is poor, and the reaction time is long, effect
Rate is low, is unfavorable for large-scale production.
Therefore, how by easy-to-use mode, surface modification is carried out to polyetheretherketonematerials materials, polyether-ether-ketone material is improved
The biocompatibility and antibiotic property of material, have become one of study hotspot.
