摘要

本研究的主要目的是探讨各种电纺丝参数对纤维素纳米纤维(CNF)填充聚乳酸(PLA)纳米纤维的形态和直径的影响。为此,首先研究了三个重要电纺参数的影响:聚合物溶液浓度、溶液喂料速率和集电极到喂料头的距离。然后,还研究了使用更多 CNF 的影响、使用纤维素纳米晶(CNC)颗粒的影响以及添加氯化钾盐的影响。结果表明,在确定了最佳电纺参数后,聚乳酸/氯化萘电纺纤维可获得几乎 "无珠 "的形态和 232 nm 的 "最细 "平均直径。增加喂料速率和集电极间距参数值会导致形成珠状物和更粗的直径。另一方面,增加 CNF 的用量、使用 CNC 颗粒和添加 KCl 盐都会导致直径进一步减小至 152 nm,这主要是由于聚合物溶液的电荷密度增加所致。此外,对所有类型的电纺纳米纤维毡在模拟体液中的体外降解分析表明,从 "重量损失百分比 "的角度来看,浸泡时间越长,降解率越高。同时还发现,纤维直径较细的纤维毡降解率更高。

Parameters influencing electrospun nanofiber diameter of polylactide incorporated with cellulose nanofibrils and nanocrystals
The main purpose of this study was to investigate effects of various electrospinning parameters on the morphology and diameter of cellulose nanofibril (CNF) filled polylactide (PLA) nanofibers. For this purpose, first of all effects of three important electrospinning parameters; polymer solution concentration, solution feeding rate and collector distance to feeding tip were studied. Then, effects of using higher amount of CNF, effects of using cellulose nanocrystal (CNC) particles, and effects of adding potassium chloride salt were also investigated. It was observed that when optimum electrospinning parameters were determined, then it was possible to obtain almost “bead-free” morphology and “finest” average diameter of 232 nm for PLA/CNF electrospun fibers. Increasing values of feeding rate and collector distance parameters resulted in bead formation and thicker diameters. On the other hand, increasing CNF amount, using CNC particles and adding KCl salt, all resulted in further decreases in the diameter down to 152 nm; mainly due to increased charge density of the polymer solution. Moreover, in vitro degradation analysis of all types of electrospun nanofiber mats in a simulated body fluid revealed that increasing the immersion period increased their degradation rate in terms of “% weight loss”. It was also observed that, mats with fine diameter fibers had higher degradation rate.
