聚L-乳酸的热性能研究
Study on Thermal Properties of Poly(L-lactic acid)
摘要
Abstract
The non-isothermal crystallization behavior, melting behavior and thermal gravimetric progress of poly(L-lactic acid) (PLLA) were investigated in order to obtain the structure characteristics and control the processing technology of PLLA. The results show that the non-isothermal crystallization process of PLLA Is affected by cooling rate, the oneset temperature of crystallization for PLLA is 121°C , and the crystallization enthalpy is 3.363 J/g; the double-melting peaks of PLLA result from melting-recrystallizatlon; the thermal decomposition temperature of PLLA is about 300 c , which increases with the increase of heating rate.关键词
