Reversible surface wettability coatings have been researched intensively because of potential use in oil/water separation especially seriously oil spill pollution. Herein, a new system has been designed to facile fabricate a UV and thermal dual responsive coating with high adhesion and mechanical robust properties. Bisphenol A-aniline benzoxazine (B), polyacrylate (A) and mesoporous TiO2 particles (Tmes) are carefully chosen, blended and cured to form a BATmes ternary composite coating by a spraying process. Resulted coatings show in the wettability conversion from hydrophobic to hydrophilic and excellent anti-abrasion that can keep surface condition after 400?cm abrasion by using abrasive paper (240 mesh) under a pressure of 2.5?M. Meanwhile, the adhesion, toughness and hardness properties of coatings can reach to 5B, 9.8J and 6H, respectively. Using flexible polyacrylate and mesoporous TiO2 is the main reason for comprehensive excellent mechanical properties. These findings not only provide a new system for controllable wettability coatings but also offer a new approach for making mechanical robust surfaces.
