摘　　要：竹纸浆纤维(BPF)作为一种生物纤维,具有良好的生物降解性,将其与聚丁二酸丁二醇酯(PBS)制得BPF-PBS生物质复合材料,并用差示扫描量热法(DSC)研究了BPF-PBS的非等温结晶动力学,用Liu方程分析研究了复合材料的非等温结晶动力学参数。结果表明:Liu方程能够较好地表现BPF-PBS的非等温结晶过程。结晶速率随着冷却速率的增大而提高,BPF的加入缩短了结晶时间,提高了结晶度及结晶温度。碱溶液处理BPF可以增加PBS的结晶活化点,提高结晶度。Bamboo pulp fiber（BPF）,as a kind of biological fiber,had good biodegradability.The nonisothermal crystallization kinetics of BPF reinforced poly（butylenes succinate）（PBS）were studied using differential scanning calorimetry（DSC）,and Liu equation was used to determine the non-isothermal crystallization kinetic parameters of BPF-PBS bio-composite.Results show that Liu equation can well describe the non-isotheral crystallization process of BPF-PBS bio-composite.The crystallization rate increases significantly with the increase of cooling rate.The higher content of BPF used in the BPF-PBS bio-composite lead to higher crystallinity and crystallization temperature,but lower crystallization rate.Besides,the alkali treated BPF could result in higher crystallinity.
