环氧树脂因具有稳定的理化特性、自我修复能力以及对金属基材的优异附着力而被广泛用于工业生产中。利用环氧树脂与两种纳米粒子(疏水SiO2和TiO2)进行复配制备有机-无机复合涂层。相较使用单一的纳米粒子,纳米SiO2和纳米TiO2的共同使用能更好地提升环氧树脂复合涂层的疏水性和自清洁性。此外,这种通过复配制备超疏水涂层的方法生产成本低,制备步骤简便,对设备要求低且适合大面积制备。
Epoxy resin is widely employed in industrial production due to their stable physicochemical properties,self-healing ability,and excellent adhesion to a metal substrate.The organic-inorganic composite coatings were prepared by mixing epoxy resin with two kinds of nanoparticles (hydrophobic SiO2 and TiO2).Compared with the use of single nanoparticles,the combined use of nano-SiO2 and nano-TiO2 can better improve the hydrophobicity and self-cleaning property of the EP composite coatings.In addition,the superhydrophobic coatings prepared by this method exhibited low production costs,simple procedure,low equipment requirements and suitable for large area preparation.
