摘要
玻璃表面微纳结构的设计和制造在实现所需功能方面具有重要意义.然而,玻璃固有的硬度和脆性给传统制造方法带来了不便.因此,开发一种简单且可控的制造策略对于制备具备功能应用的微纳结构玻璃至关重要.在本文中,我们提出了一种创新方法,利用可溶性氯化钠颗粒作为前驱体模板,在玻璃表面上创建可定制的多孔结构.通过我们的先导成型策略,成功利用可溶性氯化钠颗粒的潜力作为前驱体模板,从而便于制造量身定制的多孔玻璃表面.通过调节这些颗粒的大小和组合,我们实现了对所得多孔玻璃的连续调控,范围从超亲水(1°)到超疏水(142°).值得注意的是,制备的多孔玻璃表面表现出显著的亲油性,展示了在油水分离和自清洁等多种应用方面的巨大潜力.最重要的是,即使经过了10次制造迭代,玻璃表面的疏水-亲油功能依然完好,凸显了我们策略的耐久性和可重复性.这种方法为实现玻璃的特殊功能提供了方便且具有成本效益的途径,为不同领域的进展铺平了道路.
Micro-and nano-structures are a new type of material structures that combines micrometer-and nano-meter-scale structures in a single material,which confers special properties on the material.Designing and fabricating micro-and nano-structures on glass surfaces hold great im-portance for achieving desired functionalities.However,the inherent hardness and brittleness of glass pose challenges for preparing micro-structures using traditional fabrication methods.Thus,developing a simple and controlled manu-facturing strategy becomes imperative to prepare micro-and nano-structured glasses with functional applications.In this work,an innovative approach that employed soluble NaCl particles as precursor templates was presented,allowing the formation of customizable porous structures on glass surfaces.Using the pioneering molding strategy proposed here,the potential of soluble NaCl particles as templates was success-fully harnessed,thereby facilitating the fabrication of tailor-able porous glass surfaces.By tuning the size and combination of these particles,porous glasses ranging from super-hydrophilic(1°)to superhydrophobic(142°)were achieved.Notably,the prepared porous glass surfaces demonstrated remarkable lipophilicity,highlighting its great potential for diverse applications,such as oil-water separation and self-cleaning.Importantly,even after undergoing 10 fabrication iterations,the hydrophobic-oleophilic functionality of the glass surface remained intact,underscoring the durability and repeatability of our strategy.This approach offers a con-venient and cost-effective means to achieve special functions in glass,paving the way for advancements across various fields.
