Abstract

The one-dimensional structure preparation by electrospinning method is one of the most important especially since it can get fine diameters of fibers. Poly (vinyl alcohol) and (PVA)/polyethylene glycol (PEG) were mixed to get the blend and doped with different ratios (0.001, 0.002, 0.003) wt.% of calcium fluoride (CaF₂) to get nanocomposite were fabricated using the electrospinning method at RT and voltage of 23 kV. Structural and optical properties were studied and the antibacterial activity was examined. The result of SEM analysis showed that the polymer blend and doped samples produced a random distribution with fine fibers at an average diameter range before CaF₂ addition to be 68.97 nm and after CaF₂ addition for each sample to be 45.76, 68.71, and 98.45 nm with a smooth surface. XRD analysis confirmed the existence of semi-crystalline PVA and PEG aggregates, and the CaF₂ cubic crystalline phase appears when an additive of CaF₂ nanoparticles up to 0.003 g. Absorbance spectra were recorded in the wavelength range of (200–800) nm. Absorption increased by two times when doping of CaF₂ increased to 0.003 wt.%. The optical energy gap of fabricated films decreased with increasing CaF₂ nanoparticles from (3.6–3.3) eV, while the refractive index increased. Increasing the content of NPs for the (PVA-PEG:CaF₂) nanofibers mixture leads to an increase in the diameter of the inhibition zone for Escherichia coli for antibacterial activity.

通过电纺丝技术制备一维结构聚（乙烯醇）-聚乙二醇：氟化钙纳米复合材料：表征和抗菌应用

电纺丝法制备一维结构是最重要的方法之一，尤其是因为它可以获得细直径的纤维。将聚（乙烯醇）和（PVA）/聚乙二醇（PEG）混合得到混合物，然后掺入不同重量比（0.001、0.002、0.003）的氟化钙（CaF2），利用电纺丝方法在 RT 和 23 kV 电压下制成纳米复合材料。研究了纳米复合材料的结构和光学特性，并考察了其抗菌活性。扫描电镜分析结果表明，聚合物混合物和掺杂样品产生了随机分布的细纤维，添加 CaF2 前的平均直径范围为 68.97 nm，添加 CaF2 后每个样品的平均直径范围分别为 45.76、68.71 和 98.45 nm，表面光滑。XRD 分析证实了半晶体 PVA 和 PEG 聚集体的存在，当 CaF2 纳米粒子的添加量达到 0.003 克时，出现了 CaF2 立方晶体相。当 CaF2 的掺杂量增加到 0.003 wt.% 时，吸收率增加了两倍。随着 CaF2 纳米粒子含量的增加，制备薄膜的光学能隙从 (3.6-3.3) eV 下降，而折射率增加。增加（PVA-PEG:CaF2）纳米纤维混合物中的 NPs 含量可增加大肠杆菌抗菌活性抑制区的直径。

期刊介绍： "Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad. "Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
