应用于多孔生物陶瓷自增强纤维制备与形貌控制

Preparation and Morphology Control of Fiber Used in Reinforcing Porous Biological Ceramics

羟基磷灰石(Hydroxyapatite,HAP)的硬组织生物相容性和骨传导及生物活性而常被用于制备生物陶瓷,但多孔形式的HAP抗压强度较低,研究提出了用于多孔HAP陶瓷增强的同质纤维制备和形貌控制。首先配制HAP纺丝液,通过溶胶挤压喷纺制成HAP初生纤维,经烘箱干燥后或拉伸或进行其它后处理,对HAP纤维进行形貌控制,并确定了各项工艺要素。

Due to the hard tissue biocompatibility, osteoconduction and biological activity, Hydroxyapatite （HAP） is often used in the preparation of biological ceramics. But the porous HAP exhibits low strength in compression. This study presents the preparation of homogeneous fiber and morphology control to reinforce the porous HAP ceramics. First, the HAP spinning solution is prepared and made into HAP primary fiber through sol extrusion and injection. After being dried in oven, the HAP fiber will have morphology control by stretching or other after-treatment. And various technological oarameters will be determined.
