Latest Patents

One of his latest patents is titled "Fabrication of aligned crystal cell/film by simultaneous alignment and phase separation." This invention discloses a method for simultaneously fabricating a phase-separated organic film and microstructures with liquid crystal that has the desired alignment. The process involves preparing a mixture of liquid crystal material, prepolymer, and polarization-sensitive material, which is then disposed on a substrate. A combination of UV or visible light or heat treatment is applied while inducing phase separation to form a layer or microstructure of appropriately aligned liquid crystal material adjacent to the substrate.

Another notable patent is "Electrically controllable liquid crystal microstructures." This invention relates to methods of building rigid or flexible arrays of electro-optic devices. The technique yields adjacent regions of polymer and liquid crystal (LC) of specific architecture instead of a random dispersion of LC droplets. The devices can be prepared by producing volutes of LC structure next to a polymer area using anisotropic phase separation of LC from a photopolymer, initiated by UV exposure. The shape, size, and placement of these regions inside a cell become easily controllable using an optical mask or laser beam.
