| titleOfInvention | Preparation method of waterborne polyurethane/collagen/hydroxyapatite composite material |
| abstract | The invention discloses a preparation method of a waterborne polyurethane/collagen/hydroxyapatite composite material, which comprises the following components in parts by weight: diisocyanate, polyester polyol, a chain extender, an aqueous chain extender, a neutralizer, hydrolyzed collagen liquid, gamma-glycidyl ether oxypropyltrimethoxysilane (KH 560), calcium chloride and disodium hydrogen phosphate. According to the invention, polyester type Waterborne Polyurethane (WPU) prepolymer and biochemical Gelatin Hydrolysate (GH) are subjected to emulsion polymerization reaction, and further external crosslinking modification is carried out through KH560 to improve the hydrophobicity and the adhesive film toughness of the material, so as to prepare WPU and GH graft copolymer composite emulsion (WPU-g-GH). Aims to prepare the nano HAP composite material with good mechanical property, structural stability, biocompatibility and degradability, so that the nano HAP composite material is expected to become a potential bone scaffold repairing material. |
