Synthesis and Characterization of Poly( ethylene glycol)/hydroxyapatite Hybrid Nanomaterials
摘要
Abstract
Poly(ethylene glycol ether) phosphate(P-MPEG) was synthesized through phosphorylating and hy-drolyzing 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.关键词
