Abstract
Methods are provided for making layers with nano- and micro-patterned topographies by laser action or inkjet printing on a first surface. These topographies have a periodicity of 5 nm to 500 μm in a first direction in the plane of the first surface. These layers can be used as anisotropically patterned alignment layers in electro-optical devices and generate an orientational order of at least 0.30.
Claims19
A method comprising:
- providing a first surface;
- depositing a solution over the first surface via inkjet printing to form a first anisotropic pattern;
- and
- solidifying the solution to form a first anisotropically patterned alignment layer having features with a size of 5 nm to 500 μm,
- wherein the first anisotropic pattern formed by the deposition has a first periodicity of 5 nm to 500 μm in a first direction in the plane of the first surface.
