Abstract
A method of making a polarizer can include applying a liquid with solid inorganic nanoparticles dispersed throughout a continuous phase, then forming this into a different phase including a solid, interconnecting network of the inorganic nanoparticles. This method can improve manufacturability and reducing manufacturing cost. This method can be used to provide an antireflective coating, to provide a protective coating on polarization structures, to provide thin films for optical properties, or to form the polarization structures themselves.
Claims20
A method of making a polarizer, the method comprising:
- providing a polarization device on a substrate, the polarization device including objects arranged in a pattern for polarization of light, and an overcoat layer on a surface of the polarization device farthest from the substrate;
- applying an uncured cover layer to an outer surface of the overcoat layer farthest from the polarization device, the uncured cover layer being a liquid with solid inorganic nanoparticles dispersed throughout a continuous phase;
- and
- curing the uncured cover layer to form a cured cover layer, the cured cover layer including a solid, interconnecting network of the inorganic nanoparticles.
A method of making a polarizer, the method comprising:
- providing a polarization device on a substrate, the polarization device including objects arranged in a pattern for polarization of light, and an overcoat layer on a surface of the polarization device farthest from the substrate;
- applying an uncured cover layer to an outer surface of the overcoat layer farthest from the polarization device, the uncured cover layer being a colloidal suspension including a dispersed phase and a continuous phase;
- and
- curing the uncured cover layer by removing the continuous phase to form a solid, defining a cured cover layer.
A method of making a polarizer, the method comprising:
- providing a polarization device on a substrate, the polarization device including objects arranged in a pattern for polarization of light, and an overcoat layer on a surface of the polarization device farthest from the substrate;
- applying an uncured cover layer to an outer surface of the overcoat layer farthest from the polarization device, the uncured cover layer being a solution including molecules in a solvent, the solvent including water and an organic liquid, the molecules including metal atoms bonded to reactive groups, where each reactive-group is independently —Cl, —OR1, —OCOR1, or —N(R1)2, and R1 is an alkyl group;
- and
- reacting the molecules to form a solid of the metal atoms interconnected with each other, defining a cured cover layer.
