Emulsion Technique Preparation of Nano-HA/PMMA Composites and In Vitro Evaluation

Abstract:

Article Preview

Nano-sized hydroxyapatite (HA) chloroform suspensions were firstly prepared by reactions in an emulsion system of Ca(OH)2-H3PO4-chloroform-lecithin, then, HA/PMMA composites with well dispersed HA could be obtained by adding PMMA into the suspension. The residual water in the HA suspension could lead to a porous surface which demonstrated better bioactivity in in vitro test. The residual water could cause HA particles to exist on pore walls during the composite formation, resulting in the increase of the HA amount per unit surfac
