Abstract

Super-hydrophilic and oleophobic functional materials can prevent pollution or adsorption by repelling oil, and have good circulation. However, traditional strategies for preparing these functional materials either use expensive fabrication machines or contain possibly toxic organic polymers, which may prohibit the practical application. The research of multifunctional ZnO microstructures or nanoarrays thin films with super-hydrophilic, antifouling, and antibacterial properties has not been reported yet. Moreover, the exploration of underwater oleophobic and self-cleaning antifouling properties in ZnO micro/nanostructures is still in its infancy. Here, we prepared ZnO microstructured films on fluorine-doped tin oxide substrates (F-ZMF) for the development of advanced self-cleaning type super-hydrophilic and oleophobic materials. With the increase of the accelerators, the average size of the F-ZMF microstructures decreased. The F-ZMF shows excellent self-cleaning performance and hydrophilic (water contact angle ≤ 10°) and oleophobic characteristics in the underwater antifouling experiment. Under a dark condition, F-ZMF-4 showed good antibacterial effects against () and () with inhibition rates of 99.1% and 99.9%, respectively. This study broadens the application scope of ZnO-based material and provides a novel prospect for the development of self-cleaning super-hydrophilic and oleophobic materials.

摘要

超亲水疏油功能材料可以通过排斥油污来防止污染或吸附,并且具有良好的循环性能。然而,制备这些功能材料的传统策略要么使用昂贵的制造设备,要么包含可能有毒的有机聚合物,这可能会阻碍其实际应用。具有超亲水、防污和抗菌性能的多功能氧化锌微结构或纳米阵列薄膜的研究尚未见报道。此外,氧化锌微/纳米结构中水下疏油和自清洁防污性能的探索仍处于起步阶段。在此,我们在氟掺杂氧化锡衬底上制备了氧化锌微结构薄膜(F-ZMF),用于开发先进的自清洁型超亲水疏油材料。随着促进剂用量的增加,F-ZMF微结构的平均尺寸减小。在水下防污实验中,F-ZMF表现出优异的自清洁性能以及亲水(水接触角≤10°)和疏油特性。在黑暗条件下,F-ZMF-4对()和()显示出良好的抗菌效果,抑制率分别为99.1%和99.9%。本研究拓宽了氧化锌基材料的应用范围,并为自清洁超亲水疏油材料的开发提供了新的前景。
