We used supersonic aerosol deposition to fabricate transparent flexible thin “glass” films, comprising SiO₂ and ZnO, with antibacterial, superhydrophilic, and anti-fog properties. A polystyrene solution, which was supersonically sprayed onto the glass film to augment the superhydrophobicity, endowed the film with self-cleaning and anti-frost characteristics. The glass films have a thickness of 2–2.5 μm with a maximum roughness of approximately 0.25 μm. The sprayed polystyrene (PS) layer (approximately 200 nm thick) decreased the transparency of the film to 80% relative to that of the pure glass film (90%) at 580 nm. The large water contact angle of 165° renders the PS-coated glass film superhydrophobic, which slows the nucleation of condensing droplets and delays the subsequent formation of ice, known as the anti-frost or anti-icing effect. The superhydrophobicity is also responsible for the self-cleaning effect of the rolling droplets over a tilted substrate. The hydrophilicity of the glass-coated film (or simply, glass film) without PS facilitated the formation of a thin liquid layer, which minimized light scattering and augmented the anti-fog effect. Finally, the bacterial inhibition rates of the glass and PS-coated glass films were 97.5% and 96.3%, respectively. These multifunctional films are expected to minimize the transmission of bacteria resulting from physical contact.

我们使用超音速气溶胶沉积来制造透明的柔性薄“玻璃”薄膜，包括 SiO ₂和 ZnO，具有抗菌、超亲水和防雾特性。将聚苯乙烯溶液超声喷涂到玻璃膜上以增强超疏水性，使膜具有自清洁和防霜特性。玻璃膜的厚度为 2-2.5 μm，最大粗糙度约为 0.25 μm。相对于纯玻璃膜 (90%) 在 580 nm 处，喷涂的聚苯乙烯 (PS) 层（约 200 nm 厚）将膜的透明度降低至 80%。165°的大水接触角使涂有PS的玻璃膜具有超疏水性，这减缓了冷凝液滴的成核并延迟了随后的冰的形成，称为防霜或防冰效果。超疏水性也是导致滚动液滴在倾斜基底上产生自清洁效果的原因。不含 PS 的玻璃涂层膜（或简称为玻璃膜）的亲水性促进了薄液层的形成，从而最大限度地减少了光散射并增强了防雾效果。最后，玻璃和PS涂层玻璃膜的细菌抑制率分别为97.5%和96.3%。这些多功能薄膜有望最大限度地减少因身体接触而导致的细菌传播。分别。这些多功能薄膜有望最大限度地减少因身体接触而导致的细菌传播。分别。这些多功能薄膜有望最大限度地减少因身体接触而导致的细菌传播。
