US 11,959,187 B2 · Antireflective synthetic brochosomal coatings

Abstract

Synthetic brochosomes can be prepared by disposing a monolayer of first polymer microspheres on a substrate and forming a layer of metal on the monolayer of the first polymer microspheres. A monolayer of second polymer microspheres is then disposed on the layer of metal to form a template. The second polymer microspheres are smaller than the first polymer microspheres. A brochosome material is then electrodeposited on the template. The brochosome material is selected from the group consisting of a metal, a metal oxide, a polymer or a hybrid thereof. The first polymer microspheres and the second polymer microspheres are then removed to form a coating of synthetic brochosomes of the brochosome material on the substrate.

Dependent claims

A method of making a synthetic brochosome, the method comprising:

a) forming a spherical portion of a material that is capable of receiving an electrodeposition-compatible material, the spherical portion having an interior surface, the interior surface having a shape that is at least a portion of a first sphere having a first diameter;
and
b) radially depositing a plurality of outgrowths of the electrodeposition-compatible material from the spherical portion, thereby forming the synthetic brochosome, the plurality of outgrowths defining a plurality of indentations, the radially depositing being outward from the interior surface and around a plurality of removable structures, each indentation having a shape that is a negative imprint of one of the plurality of removable structures, the plurality of indentations each having a second diameter,
wherein the second diameter is smaller than the first diameter.
