摘    要:
研究了制备聚乙烯醇(PVA),羟基磷灰石(HA)复合水凝胶的沉淀法原位复合技术,对该法制备的复合水凝胶的力学强度、结晶性能和微观形貌进行了分析,并与物理共混法加以比较。结果表明,沉淀法原位复合技术可在PVA水凝胶基体中合成得到粒度细,分散好的晶相HA陶瓷微粒,复合后水凝胶的结晶度和拉伸强度比之基体试样均有大幅度提高。

关 键 词:羟基磷灰石(HA) 聚乙烯醇 沉淀法 原位复合 性能研究 复合水凝胶 结构 复合技术 微观形貌 物理共混 结晶性能 力学强度 PVA 强度比 结晶度 基体 制备

Abstract:
In this paper,the compounding in situ by precipitation to prepare Poly(vinyl alcohol)/Hydroxyapatite compound hydrogel was investigated.The tensile strength,crystallinity,and micromorphology of compound hydrogel were measured and observed.It was founded that the compounding in situ by precipitation can obtain ultrafine granular_crystalline of HA dispersed evenly in matrix compared with mechanical mix method.The crystallinity and tensile strength of compound hydrogel were highly increased.
Keywords:hydrogel  poly(vinyl alcohol)  hydroxyapatite  compounding in situ by precipitation
