| 中文摘要 | five n,n'-bis(benzoyl) alkyl diacid dihydrazides were synthesized from benzoyl hydrazine and alkyl diacyl dichloride which were derived from alkyl diacid via acylation. plla/n,n'-bis(benzoyl) alkyl diacid dihydrazide samples were prepared by melt blending and hot-press forming process. the nucleation effect of n,n'-bis(benzoyl) alkyl diacid dihydrazide on crystallization of biodegradable poly(l-lactic acid) (plla) was investigated using differential scanning calorimetry (dsc) and vicat softening analysis. the results showed that five n,n'-bis(benzoyl) alkyl diacid dihydrazides acted as powerful nucleating agent for plla; with incorporation of n,n'-bis(benzoyl) alkyl diacid dihydrazide, the crystallization peak became sharper and shifted to higher temperature as the degree of supercooling decreased at a cooling rate of 1 degrees c/min from melt. the nucleation activities of five n,n'-bis(benzoyl) alkyl diacid dihydrazides were quantitatively determined. it is shown that n,n'-bis(benzoyl) suberic acid dihydrazide has higher nucleating activity than the other n,n'-bis(benzoyl) alkyl diacid dihydrazides. in the presence of n,n'-bis(benzoyl) alkyl diacid dihydrazide, the melting behavior of plla is affected significantly. in addition, the thermal stability of plla/0.8 % n,n'-bis(benzoyl) alkyl diacid dihydrazide is tested and reported. compared to the neat plla, the onset degradation temperature of plla/0.8 % n,n'-bis(benzoyl) alkyl diacid dihydrazide samples has been decreased significantly. |
