Abstract

In this study, nanofibers of poly (acrylic acid) (PAAc), polyacrylamide (PAAm) and poly (vinyl alcohol) (PVOH) were prepared using the electrospinning technique. Based on the Taguchi DOE (design of experiment) method, the effects of electrospinning parameters, i.e., needle tip to collector distance, polymer solution concentration, applied voltage, polymer solution feed rate and polymer type, on the diameter and morphology of polymer nanofibers were evaluated. Analyses of the experiments for the diameters of the polymer nanofibers showed that the type of polymer was the most significant factor. The optimal combination to obtain the smallest diameters with minimum deviations for electrospun polymer nanofibers was also determined. For this purpose, the appropriate factor levels were determined as follows: polymer PAAm, applied voltage 10 kV, delivery rate 0.1 mL/h, needle tip to collector distance 10 cm, and polymer solution concentration 8%, to obtain the thinnest nanofibers. This combination was further validated by conducting a confirmation experiment, and the average diameter of the polymer nanofibers was found to be close to the optimal conditions estimated by the Taguchi DOE method.

摘要

在本研究中，采用静电纺丝技术制备了聚丙烯酸（PAAc）、聚丙烯酰胺（PAAm）和聚乙烯醇（PVOH）的纳米纤维。基于田口实验设计（DOE）方法，评估了静电纺丝参数，即针尖到收集器的距离、聚合物溶液浓度、施加电压、聚合物溶液进料速率和聚合物类型，对聚合物纳米纤维直径和形态的影响。对聚合物纳米纤维直径的实验分析表明，聚合物类型是最显著的因素。还确定了获得最小直径且偏差最小的电纺聚合物纳米纤维的最佳组合。为此，确定了合适的因素水平如下：聚合物PAAm、施加电压10 kV、输送速率0.1 mL/h、针尖到收集器的距离10 cm以及聚合物溶液浓度8%，以获得最细的纳米纤维。通过进行确认实验进一步验证了该组合，发现聚合物纳米纤维的平均直径接近田口DOE方法估计的最佳条件。
