In this investigation, the laser marker ablation technique was employed on Cu-coated glass to fabricate micro-nanostructured antifog glass. The resulting surfaces exhibited a quasi-periodic micron hillock-hollow structure with dispersed nanoparticles distributed throughout, which played a role in the antifog property and superhydrophilicity. However, airborne organic pollutant deposition degraded the superhydrophilicity of ablated glass surfaces and, therefore, their antifog performance, which cannot be circumvented. Conventionally, furnace annealing for at least 1 h was used to decompose the organic pollutants and restore the superhydrophilicity, limiting the throughput and application scenario. Remarkably, the rapid regeneration of this property was achieved through either a 5 min rapid thermal treatment at 400 °C or a 1 s flame treatment. These are interventions that are hitherto unreported. Such short and simple treatment methods underscore the potential of laser-ablated glass for diverse practical applications.
在本研究中，采用激光标记烧蚀技术在镀铜玻璃上制备微纳结构防雾玻璃。所得表面呈现出准周期性的微米级小丘-空洞结构，且有分散的纳米颗粒遍布其中，这些纳米颗粒对防雾性能和超亲水性起到了作用。然而，空气中有机污染物的沉积会降低烧蚀玻璃表面的超亲水性，进而影响其防雾性能，这是无法避免的。传统上，至少1小时的炉内退火用于分解有机污染物并恢复超亲水性，这限制了产量和应用场景。值得注意的是，通过在400℃下进行5分钟的快速热处理或1秒的火焰处理，可实现这种性能的快速再生。这些都是迄今未报道过的干预措施。如此简短且简单的处理方法凸显了激光烧蚀玻璃在各种实际应用中的潜力。
