Polymer composite photonic crystal materials are disclosed as coatings with topcoats having high reflection (>30%) in a specific range of the electromagnetic spectrum, such as ultraviolet (<400 nm), visible (Vis, 400 nm-700 nm), or near-infrared radiation range (NIR, 700-2000 nm), and optionally a relatively low reflection (<20% reflection) in a second, different range of the electromagnetic spectrum. Surprisingly, it was found that through a multi-layer coating approach, the optical properties of polymer composite photonic crystal films can be selectively modified from a variety of different coating methods, including spray deposition.

Provided are a non-stick coating, a non-stick coating material group, and a cooking device. The non-stick coating includes: an undercoat, a hue of at least one material in the undercoat being adapted to shield a hue of a substrate material; and a topcoat disposed on a surface of the undercoat facing away from the substrate material, the topcoat including a fluorine-containing resin.
