| Abstract: | Aqueous polyurethane （WPU） emulsion is synthesized through an acetone method using polyethylene glycol and poly （caprolactone dibasic alcohol） as soft segment, lysine as chain extender with isophorone diisocyanate. Its solid contents are 10%. Waterborne polyurethane/hydroxyapatite composite material is prepared using a physical mixing method which mixes the WPU emulsion with nHA. The structure and properties of composites are characterized and discussed by X-ray diffraction（XRD）, tensile test, contact angle test and water absorption test. |
