摘要/Abstract

摘要： 静电纺丝制备的纳米纤维孔隙率高、吸附能力强，可用于高效地处理化工行业油污染问题。聚乳酸（PLA）作为生物可降解材料，来源广泛且不会造成二次污染，具有广阔的应用前景。本文利用自制的熔体微分电纺装置，制备了PLA/乙酰基柠檬酸三丁酯（ATBC）纤维膜，探究了物料性质和增塑剂ATBC含量对PLA纤维形貌及吸油性能的影响，并获得了最佳的纺丝温度和ATBC含量。研究表明，在纺丝温度为240℃、ATBC质量分数为10%时制备的纤维直径为320nm。该纤维膜水接触角为145°，表现出良好的疏水性能，吸油倍率为138.4g/g，是市售PP无纺布吸油性能的4～5倍，保油倍率为85.8g/g。重复吸/放油5次循环后，纤维膜仍具有良好的强度而未发生断裂且可继续进行吸油，重复使用性能较好，可被应用于化工行业油污染处理。

Abstract: Nanofibers prepared by electrospinning have high porosities and strong adsorption capacities and thus are useful for treating the oil pollution in chemical industry. As a biodegradable material,polylactide(PLA) has a wide range of sources and broad application potentials. In addition,it does not cause second pollution. The PLA/acetyl tributyl citrate(ATBC) nanofiber films are prepared by using a self-made melt differential electrospinning device. The material properties and effects of plasticizer ATBC content of PLA nanofiber films on the morphology and the oil absorption properties are investigated. And the optimum spinning temperature and ATBC content are obtained. The research shows that when the spinning temperature is 240℃ and the ATBC content is 10%, the diameter of the fiber reaches 320nm. And the water contact angle of the nanofiber film is 145°, which shows good hydrophobicity. The oil absorption rate of the nanofiber film is 138.4g/g, which is 4-5 times higher than that of commercially available PP nonwovens,and the oil holding rate is 85.8g/g. After 5 times oil absorption and discharge,the nanofiber film still has good strength without breaking and can continue to absorb oil. It indicates that the nanofiber film has good reuse performance and can be used in the oil pollution treatment in chemical industry.
