Effects of Surface Modification on Dispersion, Mechanical, Thermal And Dynamic Mechanical Properties Of Injection Molded PLA-hydroxyapatite Composites

Effects of Surface Modification on Dispersion, Mechanical, Thermal And Dynamic Mechanical Properties Of Injection Molded PLA-hydroxyapatite Composites

In this study, poly(lactic acid) (PLA)/hydroxyapatite (HA) composites were produced through extrusion and injection moulding. In order to foster good interaction between PLA and HA, a phosphate based modifier (Fabulase(R) 361) was used to modify the HA surface. Spectroscopic analysis reveals that su...
