| 摘 要： | 本文采用静电纺丝法制备了聚乳酸(PLA)纳米纤维毡片,并首次研究了PLA纳米纤维微观结构对材料吸油性能的影响机制。扫描电子显微镜(SEM)表征显示前驱体溶液浓度对PLA静电纺丝纳米纤维直径具有显著影响,较高的浓度导致纳米纤维直径变大,10wt.%的前驱体溶液浓度可获得直径为50~100nm的均匀纳米纤维。接触角测定发现优化后的PLA纳米纤维材料具有超疏水超亲油特性。系统研究了PLA静电纺丝纳米纤维毡片对柴油、润滑油和植物油的吸附性能,发现PLA静电纺丝纳米纤维对柴油、润滑油和植物油的最大吸油倍率分别达到37、116和51g/g。实验模拟发现所制备的PLA纳米纤维材料具有吸油倍率高,吸水率低和可生物降解等特点,可用于吸附水面溢油。

| Abstract: | Polylactic acid(PLA)nanofiber mats were successfully fabricated by an electrospinning technique.The effect of PLA nanofiber microstructure on oil absorption was investigated.Scanning electron microscope characterization show s that the precursor solution concentration plays an important role on the morphologies of PLA nanofibers,and higher PLA concentration can lead to the larger nanofiber diameter.The contact angle measurement indicates that PLA nanofiber exhibits both superhydrophobic and super-oleophilic properties.The oil-absorption experiment shows that the absorption capacity of the PLA nanofibers for lubricating oil,diesel oil and vegetable oil are 116g/g,35g/g and 45g/g,respectively.Hence,our PLA nanofiber mat exhibits high oil absorption rate,low water absorption rate and biodegradability,which is suitable to the absorption of spilled oil. |
