Abstract

Abstract: Poly(ethylene glycol ether) phosphate(P-MPEG) was synthesized through phosphorylating and hydrolyzing using poly(ethylene glycol methyl ether)(MPEG) as raw material. Then hybrid material with nHA core and polymer shell was synthesized through precipitation with P-MPEG as the steric hindrance agent. The nHA was characterized by Fourier transform infrared spectroscopy(FTIR), X-ray diffraction(XRD), transmission electron microscopy(TEM) and laser particle size analyzer(LPSA). The synthesized hybrid material is redispersible not only in water, but also in organic solvents such as methanol, N,N-dimethylformamide(DMF), etc. Feasibility of nHA with excellent redispersible ability using organic phosphate as the steric hindrance agent was confirmed.

Key words: Poly(ethylene glycol ether)phosphate, Steric hindrance effect, Nanohydroxyapatite, Redisperse
