| Abstract: | s The rheological behavior,spinning formation and biodegradability of poly(L-lactic acid)(PLLA)were studied.The result showed the melt flow of PLLA was a false-plasticity fluid.PLLA had good extrusion forming,with a non-Newtonion index of 0.93.In addition,the results of the degradation of PLLA in different environments showed PLLA was an excellent biodegradable material for medical treatment and environmental protection. |
