| 中文摘要 | a novel method of grafting ring-opening polymerization of l-lactide (lla) onto the surface of hydroxyapatite nano-particles (n-hap) was developed. plla was directly connected onto the hap surface through a chemical linkage. the plla-g-hap particles could be stably dispersed in organic solvent such as chloroform for several weeks. the n-hap particles still retained the original dimension and shape after the grafting of plla. compared with the p-31 mas-nmr spectrum of pure hap powders, there appeared a downfield displacement of 1.2 ppm in the spectrum of plla-g-hap. fourier transformation infrared (ft-ir) spectra further confirmed the existence of plla on the surface of plla-g-hap. the amount of grafted polymer determined by thermal gravimetric analysis (tga) was about 6% in weight. the tensile strength and elongation at break of the plla/plla-g-hap composite containing 8 wt% of plla-g-hap were 55 mpa and about 10-13%, respectively, while those of the plla/n-hap composites were 40 mpa and 3-5%, respectively. |
