Abstract
The present invention relates to polymer stabilized nematic liquid crystal microlenses. The microlenses can be made from a nematic liquid crystal, a chiral dopant, a reactive monomer, and a photoinitiator. The microlenses can be prepared by spin coating a liquid crystal mixture onto an array including a nickel transmission electron microscope grid. The focal length of the microlens array can be tuned electrically.

A composition for making a polymer stabilized nematic liquid crystal microlens, the composition comprising a nematic liquid crystal, a chiral dopant, a reactive monomer, and a photoinitiator, and a chiral ferroelectric nematic material.
A method of preparing polymer stabilized nematic liquid crystal microlenses, the method comprising steps of
- providing a liquid crystal mixture including a nematic liquid crystal, a chiral dopant, a reactive monomer, and a photoinitiator;
- applying the liquid crystal mixture to a grid;
- spin coating the grid having the liquid crystal mixture to thereby form a spin coated assembly;
- and
- allowing polymerization of the reactive monomer of the spin coated assembly to thereby prepare the polymer stabilized nematic liquid crystal microlenses.
