摘要Both thermochromic and photochromic coating have attracted many attentions due to their widely applications,but the low stability is a big obstacle.Inspired by the lotus leaf,to endow the chromic coating with superhydrophobicity is a possible solution.In this research,a dual response coating was prepared by adding photochromic and thermochromic particles simul-taneously.The prepared sample demonstrated at least four-state color switching,which can be successfully used in tactile imaging,multi-color fabric,erasable record,and security labels.The superhydrophobicity was achieved by introducing vinyl-terminated polydimethylsiloxane,which not only offers low surface energy but also can cross-link with the particles to increase the adhesion.Thus,the prepared sample maintained superhydrophobicity after various kinds of destruction(such as sandpaper abrasion,corrosive liquid attack,ultrasonic treatment,UV irradiation,and high-speed drops/turbulent jets impact).Even though the superhydrophobicity can be destroyed by plasma etching,it can be recovered after 12 h at room temperature.
