Abstract

The invention discloses a nano particle@graphene/polyether-ether-ketone composite material and a preparation method and application thereof. The nano particle@graphene/polyether-ether-ketone compositematerial is prepared by polyether-ether-ketone, carbon fibers, graphene and inorganic nano particles. The preparation method includes: using nano-zirconia, nano-hydroxyapatite and the graphene to prepare a ZrO2@GO hybrid material and a HA@GO hybrid material, sufficiently mixing the polyether-ether-ketone, the carbon fibers, the ZrO2@GO hybrid material and the HA@GO hybrid material, pouring the mixed material into a mould, and performing hot pressing sintering forming. The nano particle@graphene/polyether-ether-ketone composite material and the preparation method thereof have the advantages that the prepared nano particle@graphene/polyether-ether-ketone composite material is good in biocompatibility, low in friction coefficient, good in wear resistance, capable of satisfying the requirements of joint prosthesis materials, capable of being produced into joint prosthesis and capable of at least doubling the service life of the joint prosthesis as compared with traditional joint prosthesis prepared by high-molecular-weight polyethylene materials.

Description

technical field [0001] The invention relates to a polyetheretherketone composite material and its preparation method and application, in particular to a nanoparticle@graphene / polyetheretherketone composite material and its preparation method and application, belonging to the technical field of polymer composite materials. Background technique [0002] With the improvement of people's quality of life, medical care and rehabilitation, people's requirements for the performance of artificial joint materials are getting higher and higher. Traditional high molecular weight polyethylene composite materials are difficult to meet the requirements of service life and stability of artificial joints. Therefore, the development of polyether ether ketone composites as artificial joint materials has important application prospects. [0003] High-performance special engineering plastic polyether ether ketone has the characteristics of excellent self-lubricating performance, corrosion resis...
