| 中文摘要 | composite fibers composed of poly(l-lactide)-grafted hydroxyapatite (pla-g-hap) nanoparticles and polylactide (pla) matrix were prepared by electro-spinning. environmental scanning electron microscope (esem) and transmission electron microscopy (tem) were employed to investigate the morphology of the composite fibers and the distribution of pla-g-hap nanoparticles in the fibers, respectively. at a low content (similar to 4 wt%) of pla-g-hap, the nanoparticles dispersed uniformly in the fibers and the composite fibrous mats exhibited higher strength properties, compared with the pristine pla fiber mats and the simple hydroxyapatite/pla blend fiber mats. but when the content of pla-g-hap further increased, the nanoparticles began to aggregate, which resulted in the deterioration of the mechanical properties of the composite fiber mats. the degradation behaviors of the composite fiber mats were closely related to the content of pla-g-hap. at a low pla-g-hap content, degradation may be delayed due to the reduction of autocatalytic degradation of pla. when pla-g-hap content was high, degradation rate increased because of the enhanced wettability of the composite fibers and the escape of the nanoparticles from fiber surfaces during incubation. |
