Anti-fog coatings and related articles, compositions, and methods are generally described. In some embodiments, an article may comprise a dual functional anti-fog and anti-fouling coating. The coating may be stimuli-responsive and the surface energy, and accordingly wettability, of the coating may reversibly change upon exposure to certain conditions. For instance, upon exposure to water, the coating may have a relatively high surface energy that allows water to wet the coating. Conversely, exposure to an oil may cause the coating to have a relatively low surface energy that repels the oil. In some embodiments, such a stimuli responsive coating may comprise a cross-linked polymer network with covalently attached oleophobic groups.
本文主要描述了防雾涂层及相关物品、组成和方法。在某些实施例中,一种物品可以包括具有双重功能的防雾和防污涂层。该涂层可以对刺激做出反应,涂层的表面能量和润湿性可以在暴露于某些条件下可逆地改变。例如,暴露于水中时,涂层可能具有相对较高的表面能量,使水可以润湿涂层。相反,暴露于油中可能会使涂层具有相对较低的表面能量,从而排斥油。在某些实施例中,这种刺激响应涂层可以包括具有共价连接的疏水基团的交联聚合物网络。
