Abstract
The physical and chemical properties of surfaces can be controlled by bonding nanoparticles, microspheres, or nanotextures to the surface via inorganic precursors. Surfaces can acquire a variety of desirable properties such as antireflection or reflection, antifogging, antifrosting, UV blocking, and IR absorption, while maintaining transparency to visible light. Micro or nanomaterials can also be used as etching masks to texture a surface and control its physical and chemical properties via its micro or nanotexture.
Claims18
A method comprising:
- functionalizing a surface with a monolayer of a first functional group by contacting a first fluid to the surface;
- removing an excess quantity of the first fluid once the monolayer of the first functional group is formed on the surface;
- functionalizing a first plurality of particles with a second functional group by contacting a second fluid to the first plurality of particles, the second functional group chosen so as to attach to the first functional group;
- removing an excess quantity of the second fluid once the second functional group has functionalized the first plurality of particles;
- forming a single monolayer of particles on the surface, by contacting the functionalized first plurality of particles to the functionalized surface and attaching the first functional group to the second functional group;
- self-saturating the single monolayer of particles, thus preventing additional particles of the functionalized first plurality of particles from attaching to the single monolayer of particles,
- wherein:
- the particles of the first plurality of particles have lateral dimensions less than 100 micrometers.
