CH-S04对熔体微分电纺聚乳酸纤维的增强改性研究
Study on enhancement modification of melt-differential electrospun poly(lactic acid)fiber with CH-S04
摘要
Abstract
In this study,an organic-inorganic compounded nucleating agent(CH-S04)was used to enhance the mechani-cal properties of poly(lactic acid)(PLA)microfibers.The non-isothermal crystallization behavior of the resultant PLA/CH-S04 fiber films as well as the action mechanism of CH-S04 in the multistage drafting process were studied under dif-ferent spinning temperatures and voltages,and their mechanical properties of PLA/CH-S04 fiber films were character-ized.The results indicated that when the spinning temperature was 220℃and the spinning voltage was 50 kV,the de-grees of crystallinity of PLA/CH-S04 fiber films reached maximum values of 27.12%at a spinning temperature of 220℃and 32.32%at a spinning voltage of 50 kV,which were 18.53%and 23.73%higher than that of pure PLA fi-ber film,respectively.In different spinning receiving forms,CH-S04 achieved the best crystallization enhancing effect on PLA when applying voltage and air flow together with collecting by a roller.The resulting PLA/CH-S04 fiber film ob-tained a degree of crystallinity of 36.66%,which was 28.07%higher than that of pure PLA fiber film.The PLA/CH-S04 fiber film obtained tensile strength 12.33 MPa at a spinning temperature of 240℃and a spinning voltage of 50 kV,which was 11.58%higher than that of pure PLA fiber film.关键词
