Antifouling coatings face some critical challenges toward applications, particularly poor mechanical properties, complex or expensive fabrication and non-transparency. This work reports a transparent fluorine-free antifouling coating with robust mechanical properties. Water and salt, alkali and acid solutions can slide off the coating surface (water contact angle > 105°) and remove dirt. The coating endows the substrate with remarkable protection against exposure to harsh chemical conditions, mechanical robustness against extensive abrasion and high hardness (6H–9H). The characteristics of this coating are derived from heavily cross-linking branched (3-aminopropyl)triethoxysilane with zirconium dioxide (ZrO₂) ceramic nanoparticles by using a curing agent.

ZrO2与聚硅氧烷制备的硬质耐久透明防污涂层

防污涂料在应用中面临着一些关键挑战，特别是机械性能差、制造复杂或昂贵以及不透明。这项工作报告了一种具有强大机械性能的透明无氟防污涂层。水和盐、碱、酸溶液可以从涂层表面滑落（水接触角>105°）并去除污垢。该涂层赋予基材显着的保护性能，防止暴露在恶劣的化学条件下，具有抵抗广泛磨损的机械强度和高硬度（6H-9H）。该涂层的特点源自使用固化剂将支化（3-氨基丙基）三乙氧基硅烷与二氧化锆（ZrO ₂ ）陶瓷纳米颗粒进行重度交联。
