Angle‐Independent Structurally Colored Materials with Superhydrophobicity and Self‐Healing Capability

Abstract

AbstractBioinspired structurally colored materials with superwettability have aroused considerable interest, but it is still a formidable challenge to produce large‐scale superhydrophobic photonic materials with high mechanical durability. Herein, a superhydrophobic photonic composite with angle‐independent structural colors and self‐healing capability is reported, by embedding photonic glass on a healable supramolecular polymer with hydrophobic polydimethylsiloxane segments. Superhydrophobicity of the composite originates from the migration of the supramolecular polymer around the photonic glass pigments with micro–nano structure. This superhydrophobic characteristic has long‐term stability that can maintain for months. Based on the self‐cleaning property, nonwettability and vivid angle‐independent structural colors, the composite can be applied as large‐area antifouling and coloring coatings. Moreover, the reversible hydrogen bonds endow the composite with self‐healing ability and mechanical durability properties, which is crucial to practical applications as biomimetic decorative materials and wearable devices.
