英文摘要	Traditionally, an external stimulus is necessary for a self-healing superhydrophobic coating to achieve self repairing after physical or chemical damage, and this requirement seriously restricts the practical applications of such coatings. Fortunately, a superhydrophobic paint was fabricated successfully in present work. The paint was composed of lignocellulose (LC) and silica (SiO2) with hydroxyl-enriched surfaces coupled with octadecyltriethoxysilane (OTS) via hydrogen bonds, epoxy, and polyamide resin as binders. The paint can be applied to aluminum, glass, fabric, and many other substrates. The coated substrates were further modified with OTS to obtain self-healing superhydrophobic coatings. Only 4 h were needed for the coating to restore the original chemical composition and superhydrophobicity at room temperature after it was chemically damaged. The hydrogen bonds between LC/SiO2-OH and OTS-OH provided the efficient, spontaneous, and repeatable self healing capability for the coating. The coating possessed excellent chemical resistance and withstood 12 h of corrosion in strong acidic and alkaline solutions. Meanwhile, the coating demonstrated outstanding mechanical stability and maintained its superhydrophobic character after 5 h of water jetting (40 kPa). Also, the coated fabric could also be used for reutilized oil-water separation.
