Abstract The synthesis of composite nanofibers comprised of polyacrylonitrile (PAN), zinc oxide, and hinokitiol (HT) was introduced for bactericidal exertion and dye removal. The ZnO-HT-PAN_H showed better dye-removing or antibacterial results in comparison with using either zinc oxide or HT embedded in PAN nanofibers. The resulted PAN nanofibers containing mere ZnO were proved to be holding nanoparticles loosely, which was undesirable for dye removal on account of the irretrievable distribution of particles into the liquid environment. With the gluing effect of HT, ZnO nanoparticles were bound together and thus the dye adsorption was improved. In the present study, all samples were characterized by SEM-EDS, TEM, FTIR, XRD, XPS, tensile testing, and water contact angle. The antibacterial properties were assessed against Escherichia coli and Staphylococcus aureus, presenting superior inhibition zones, revealing the synergistic actions of HT and zinc oxide. The dye removing effects, evaluated against reactive blue 19 and reactive red 195 throughout 26 h, also exhibited improved adsorption without leaching phenomena. The maximum adsorption capacity of ZnO-HT-PAN_H was 267.37 and 245.76 mg/g for RB 19 and RR 195, respectively. The composite nanofibers with antibacterial properties and dye adsorption capacity also showed excellent self-cleaning performance under UV radiation.

氧化锌纳米颗粒以桧醇为胶合剂附着在聚丙烯腈纳米纤维上，具有协同抗菌活性和有效去除染料的作用

摘要 介绍了由聚丙烯腈 (PAN)、氧化锌和桧醇 (HT) 组成的复合纳米纤维的合成，用于杀菌和去除染料。与使用氧化锌或嵌入 PAN 纳米纤维中的 HT 相比，ZnO-HT-PAN_H 显示出更好的染料去除或抗菌效果。结果证明，仅含有 ZnO 的 PAN 纳米纤维可以松散地固定纳米颗粒，由于颗粒不可恢复地分布到液体环境中，因此不利于染料去除。在HT的胶合作用下，ZnO纳米颗粒结合在一起，从而改善了染料吸附。在本研究中，所有样品均通过 SEM-EDS、TEM、FTIR、XRD、XPS、拉伸测试和水接触角进行表征。对大肠杆菌和金黄色葡萄球菌的抗菌性能进行了评估，显示出优越的抑制区，揭示了 HT 和氧化锌的协同作用。在整个 26 小时内针对活性蓝 19 和活性红 195 评估的染料去除效果也表现出改善的吸附而没有浸出现象。ZnO-HT-PAN_H对RB 19和RR 195的最大吸附容量分别为267.37和245.76 mg/g。具有抗菌性能和染料吸附能力的复合纳米纤维在紫外线辐射下也表现出优异的自清洁性能。也表现出改善的吸附，没有浸出现象。ZnO-HT-PAN_H对RB 19和RR 195的最大吸附容量分别为267.37和245.76 mg/g。具有抗菌性能和染料吸附能力的复合纳米纤维在紫外线辐射下也表现出优异的自清洁性能。也表现出改善的吸附，没有浸出现象。ZnO-HT-PAN_H对RB 19和RR 195的最大吸附容量分别为267.37和245.76 mg/g。具有抗菌性能和染料吸附能力的复合纳米纤维在紫外线辐射下也表现出优异的自清洁性能。
