Abstract

Antifouling coating faces some critical challenges towards applications, especially poor mechanical properties, complex or expensive fabrications and non-transparency. This work reports a transparent fluorine-free antifouling coating with robust mechanical property. Water, salt solution, alkali and acid solution can slide off the coating surface (water contact angle, CA>105°) and remove dirt. The coating endows remarkable protection of the substrate against exposure to harsh chemical conditions and mechanically robust against extensive abrasion and high hardness (6-9H). The characteristics of this coating is derived from heavily cross-linking branched 3-aminopropyltriethoxysilane with ZrO2 ceramic nanoparticles by a curing agent.

ZrO2与支链聚硅氧烷交联制备硬质耐用透明防污涂料

防污涂层在应用中面临一些关键挑战，特别是机械性能差、制造复杂或昂贵以及不透明。本工作报告了一种具有坚固机械性能的透明无氟防污涂料。水、盐溶液、碱和酸溶液可从涂层表面滑落（水接触角，CA>105°）并清除污垢。该涂层为基材提供了显著的保护，使其不暴露在恶劣的化学条件下，并在机械上坚固耐用，不受广泛磨损和高硬度（6-9H）的影响。该涂层的特性来源于通过固化剂将支链3-氨基丙基三乙氧基硅烷与ZrO2陶瓷纳米颗粒高度交联。

期刊介绍： The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace. Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
