Abstract

In this work, the carbon steel matrix obtained a silane coupling agent (KH550) modified rough SiO₂ coating, covering it by dip-coating method. The modified SiO₂ (K-SiO₂) coating on the carbon steel was coated with stearic acid (STA) and adjusted the proportion of SiO₂ nanoparticles and KH550 to achieve the more perfect superhydrophobic sample. It turns out that SiO₂ particles were evenly disturbuted and linked together by KH550 to form a stable structure. The K-SiO₂ coating liquid was further added a modifier of STA to achieve low surface energy, and then developed a durable and corrosion resistant coating. The superhydrophobic coating liquid was coated on the carbon steel to obtain a multifunctional superhydrophobic coating (contact angle=163°, rolling angle=1.4°), having excellent self-cleaning, adhension, durability and corrosion resistance.
