| 英文摘要 | Poly(l-lactide) (plla) was blended with various contents of poly(para-dioxanone) (ppdo; 5, 10, 15 and 20 wt%) by solution co-precipitation to modify the degradation characteristics of plla. as ppdo degrades rapidly, it can be advantageously used in blends with plla. the in vitro hydrolytic degradation of the plla/ppdo blends was studied by weight loss (wl) analysis, water absorption (wa), the thermal properties, the surface morphology and the mechanical properties of the samples in phosphate-buffered saline (ph 7.44) at 37 degrees c over 8 weeks. during the degradation process, the wl and wa increased significantly for all blends and a fenestral structure with defects was formed on the surface of blend bars as degradation progressed. meanwhile, the glass transition temperature (t-g), melting temperature (t-m), tensile strength and breaking elongation of the blends decreased with time, whereas the hydrolysis rate of the blends varied with the blend composition. compared with plla, plla/ppdo blends exhibited a higher hydrolysis rate. |
