POLY(DL-LACTIDE)/HYDROXYAPATITE COMPOSITE: (Ⅳ)SURFACE MODIFICATION OF HYDROXYAPATITE AND ITS EFFECT ON THE INTERFACIAL INTERACTION OF THE COMPOSITES

摘要: 采用3-甲基丙烯酸丙酯-三甲氧基硅烷(A-174)、聚丙烯酸(PAA)分别对羟基磷灰石(HA)表面进行改性处理,通过溶液共混、取向模压成型技术制备出直径为3.2 mm的聚DL-丙交酯(PDLLA)/HA复合棒材。上述方法由于增进了复合材料在界面的相互作用,从而引起复合材料玻璃化转变温度升高,力学性能也得到了明显的改善。

Abstract: Hydroxyapatite particles were modified by 3-(trimethoxysilyl) propyl methacrylate (A-174) and polyacrylic acid (PAA) in aqueous solutions respectively. Poly(DL-lactide)/hydroxyapatite(PDLLA/HA) composites were prepared by solution-dispersion compounding and composites rods with diameter 3.2 mm were achieved by oriented molding. Results showed that the glass transition temperature of PDLLA in composites and the bending strength of the composites were increased because of enhancement of the interfacial bonding of the composites.
