Mechanical Strong, Highly Adhesive, Recyclable and Transparent Supramolecular Silicone Coatings with Easy Water/Oil Sliding
Novel supramolecular silicone poly(urea-urethane) (SSPu) coatings with excellent mechanical performance
strong interfacial adhesion and multiple time recycling capability are developed by incorporating noncovalent bonds (2-amino-4-hydroxy-6-methylpyrimidine (UPy) quadruple hydrogen bonds) into the side chain of silicone backbone.
Abstract
Traditional silicone materials have poor mechanical properties
poor interfacial adhesion and lack the ability to be reprocessed or recycled. Herein
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 capability. Impressively
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 stability. Moreover
SSPu exhibits excellent multi-recyclability and reusability without significantly decrease of its performance. In addition to the abovementioned features
the enrichment of siloxane backbones in the surface layer endows SSPu with robust repellency to water/oil. Our strategy provides a powerful route to fabricate a new multifunctional silicone elastomer. It 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
