Abstract

How to produce and fabricate polyvinyl alcohol–chitosan (PVA/CS) electrospun nanofibers to investigate the diameter and morphology of the fibers produced by experimental design software was investigated. The effects of voltage (14.32–17.05 kV), feed rate (0.2–2 ml/min), and PVA/CS mixing ratio (50–100 wt%) were studied to obtain optimal electrospinning conditions to achieve the minimum diameter and number of beads. Central Composite Design (CCD) was used to investigate and optimize the processing factors of PVA/CS nanofiber production. The nanofibers were examined using Scanning Electron Microscopy (SEM) and Fourier-Transform Infrared Spectroscopy (FTIR). Nanofibers with diameters ranging from 40 to 250 nm were obtained. The presence of PVA/CS and functional compounds related to both substances in the resulting infrared spectra was confirmed. The results of CCD showed the effect of each variable on the diameter and quality of the fibers and finally suggested the optimal conditions.

利用响应面方法（RSM）评估聚乙烯醇-壳聚糖纳米纤维电纺丝的有效参数

研究了如何生产和制造聚乙烯醇-壳聚糖（PVA/CS）电纺纳米纤维，通过实验设计软件研究了纤维的直径和形态。研究了电压（14.32-17.05 kV）、进料速度（0.2-2 ml/min）和 PVA/CS 混合比（50-100 wt%）的影响，以获得最佳电纺丝条件，实现最小直径和珠子数量。采用中央复合设计（CCD）研究并优化了 PVA/CS 纳米纤维生产的加工因素。使用扫描电子显微镜（SEM）和傅立叶变换红外光谱（FTIR）对纳米纤维进行了检测。纳米纤维的直径范围为 40 至 250 nm。由此产生的红外光谱证实了 PVA/CS 和与这两种物质相关的功能化合物的存在。CCD 的结果显示了每个变量对纤维直径和质量的影响，并最终提出了最佳条件。
