Spider silks with periodic spindle-knots are skillful at collecting water from the foggy air. Under controlled fabrication conditions, a series of bioinspired artificial spider silks (BAS) with different sized spindle-knots are realized. Furthermore, the water collection ability of these BASs is investigated. The study is helpful for the practical application of BASs as water collecting materials.
