Abstract

The invention provides a bio-based superhydrophobic anti-icing coating with an array microstructure and a preparation method thereof. The preparation method comprises the steps that firstly, a micron-sized array structure is constructed on a metal template, then anodic oxidation treatment is carried out, then the template is adhered to an elastomer material with an adhesive, and finally, a patternon the template is copied to the surface of a bio-based polymer by hot stamping. The bio-based superhydrophobic anti-icing coating with the array microstructure and the preparation method thereof have the following advantages that template patterns can be accurately obtained by combining the common advantages of a solid template and a soft template, and a coating surface with a complex structureis prepared; renewable bio-based resources are used to replace petroleum products as raw materials, and the use of fluorine-containing materials is reduced, so that the purposes of economy and environmental protection are realized; the coating is transparent, flexible, stable and durable; and the preparation method is simple, the manufacturing cost is low, the production efficiency is high, and the preparation method is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of super-hydrophobic coatings, in particular to a bio-based super-hydrophobic anti-icing coating with an array microstructure and a preparation method thereof. Background technique [0002] Since the 1990s, domestic and foreign observations and studies on the self-cleaning of lotus leaves and the ability of water striders to glide easily in water have concluded that the wettability of the surface of an object is not only related to the chemical substances on the surface of the object, but also to the surface of the object. The conclusion related to the special structure of the surface is now accepted by the majority of superhydrophobic researchers. Usually, there are two strategies for preparing superhydrophobic surfaces: one is to chemically modify the surface with a special pattern, and the other is to chemically modify the surface with a special pattern. It is to build a multi-level structure pattern on a...
