摘要：
The present invention discloses polyetheretherketone/nano-hydroxyapatite (PEEK/NANO-HA) composites for selective laser sintering (SLS), and a preparation method thereof. The method for preparing the composites comprises steps of: selecting PEEK having a particle size of 10-100 μm, and an aqueous solution of reaction precursor 1 and an aqueous solution of reaction precursor 2, uniformly dispersing the PEEK in the aqueous solution of reaction precursor 1, adding the aqueous solution of reaction precursor 2 dropwise in the mixed solution of the aqueous solution of reaction precursor 1 and the PEEK while stirring to adjust pH of the mixed solution to 10-12, and continuously reacting or 24-48 hours. The composites obtained by the preparation method of the present invention have the advantages of good biocompatibility, homogeneous morphology and good fluidity, and are advantageous to the powdering and shaping process during SLS.
