Japanese banana leaf-imitated hydrophobic antifouling rock plate and preparation method thereof
The invention discloses a Japanese banana leaf-imitated hydrophobic antifouling rock plate and a preparation method thereof. The preparation method comprises the following steps: performing ultraviolet laser etching on the surface of a ceramic rock plate to form a micro-nano two-stage composite structure, wherein the micro-nano two-stage composite structure comprises a micron-sized groove and nano-sized particles attached to the micron-sized groove; cleaning and drying the rock plate with the micro-nano two-stage composite structure formed on the surface; sokaing the dried rock plate in an ethanol solution containing fluorosilane so as to enable fluorosilane molecules to be connected to the surface of the rock plate in the form of covalent bonds; and taking out the soaked rock plate, and conducting drying again, so as to obtain the Japanese banana leaf-imitated hydrophobic antifouling rock plate. According to the preparation method, a Japanese banana leaf-like micro-nano structure is introduced into the surface of the rock plate through ultraviolet laser etching, and the micro-nano structure is modified and coupled with fluorosilane, so that the hydrophobic and antifouling functionalization of the rock plate is promoted while the decoration of the rock plate is considered.
本发明公开一种仿芭蕉叶的疏水防污岩板及其制备方法。所述制备方法包括以下步骤：紫外激光刻蚀陶瓷岩板表面形成微纳二级复合结构；所述微纳二级复合结构包括微米级沟槽和附着于微米级沟槽的纳米级颗粒；将表面形成微纳二级复合结构的岩板进行清洗并干燥；将干燥后的岩板在含氟硅烷的乙醇溶液中浸泡以使得氟硅烷分子以共价键的形式连接在岩板表面；取出浸泡完成后的岩板并再次进行干燥，获得仿芭蕉叶的疏水防污岩板。所述制备方法通过紫外激光刻蚀将类芭蕉叶的微纳结构引入岩板表面，该微纳结构与氟硅烷改性耦合从而实现兼顾岩板装饰性的同时促进岩板的疏水防污功能化。
