Polymeric coatings that show tunable mechanical strength, healing ability of damage, and proper liquid repellency will be promising in various areas across life industry. However, the exploitation such coating materials is largely limited by their molecular design. In this work, polymeric with ion-controlled mechanics coloration damage-healing oil-sliding properties have been demonstrated based on a supramolecular design dual-cross-linked polysiloxanes. The color can adjusted coordinative metal ions metal-ligand binding abilities. Dense dynamic hydrogen bonds coordination lead to ready high durability coating. extreme smoothness flat silicone facilitates not only sliding impinging oil but also restoration topological integrity from damage. selectively patterned applied large-scale substrates diverse operations, making it feasible for versatile applications.
