主　　题：Silicong coating Supramolecular Adhesion Recyclable 

摘      要：Traditional silicone materials have poor mechanical properties,poor interfacial adhesion and lack the ability to be reprocessed or ***,we developed a novel strategy of incorporating dynamic noncovalent bonds(2-amino-4-hydroxy-6-methylpyrimidine(UPy))into side chain of silicone backbones to construct supramolecular silicone poly(urea-urethane)(SSPu)coatings with excellent mechanical performance,strong interfacial adhesion and multiple time recycling ***,the prepared SSPu is endowed with simultaneously enhanced stiffness(272.0±23.2 MPa)and toughness(8.0±2.0 MJ·m^(-3)).Besides,SSPu shows strong interfacial adhesion(up to 9.0±1.3 MPa)to diverse substrate(stainless steel,aluminum,copper,epoxy and glass)with long term ***,SSPu exhibits excellent multirecyclability and reusability without significantly decrease of its *** addition to the abovementioned features,the enrichment of siloxane backbones in the surface layer endows SSPu with robust repellency to water/*** strategy provides a powerful route to fabricate a new multifunctional silicone *** is highly anticipated that our strategy can effectively extend the service life of silicone coating which can be applied in a wide variety of areas including self-cleaning,antifouling.
