Smooth, continuous, and bead-free zinc oxide (ZnO)-loaded electrospun poly(vinyl alcohol) (PVA) nanofibers were fabricated using 8% and 10% PVA concentration in water. Scanning electron microscope images showed a significant change in fiber diameter upon the addition of ZnO powders. X-ray diffraction and Raman spectral analysis revealed the successful physical blending of ZnO in PVA. Through UV–vis spectroscopy, it was found that the optical bandgap of the ZnO:PVA composite sheets ranged from 3.15 to 3.45 eV. The immobilization of ZnO in PVA support may find use as a reusable material for photocatalytic applications.

负载氧化锌颗粒的电纺聚乙烯醇纳米纤维的制备

使用水中的8％和10％PVA浓度制备了光滑，连续且无珠粒的负载氧化锌（ZnO）的静电纺丝聚乙烯醇（PVA）纳米纤维。扫描电子显微镜图像显示，在添加ZnO粉末后，纤维直径发生了显着变化。X射线衍射和拉曼光谱分析表明ZnO在PVA中成功进行了物理共混。通过紫外可见光谱，发现ZnO：PVA复合片的光学带隙范围为3.15至3.45 eV。ZnO在PVA载体中的固定化可以用作光催化应用中的可重复使用材料。
