Abstract
A nanoparticle film is disclosed. The nanoparticle film comprises a plurality of polymerized liquid crystal monomers having an axis of alignment, and a plurality of nanoparticles disposed in the polymerized liquid crystal monomers. Each of the nanoparticles has a surface modified by a plurality of first ligands and a long axis aligned with the axis of alignment through the plurality of first ligands.
Claims20
A nanoparticle film, comprising:
- a liquid crystal polymer (LCP) host comprising a plurality of polymerized liquid crystal monomers aligned with an axis of alignment;
- and
- a plurality of nanoparticles disposed in the LCP host, wherein surfaces of the plurality of nanoparticles are modified by a plurality of first ligands, and wherein, based on the plurality of first ligands, long axes of the plurality of nanoparticles are aligned in parallel relative to the axis of alignment of the polymerized liquid crystal monomers of the LCP host.
A method of making a nanoparticle film, comprising:
- modifying surfaces of a plurality of nanoparticles with a plurality of first ligands;
- mixing the surface-modified nanoparticles with a plurality of liquid crystal monomers;
- disposing the mixture of the liquid crystal monomers and the surface-modified nanoparticles on an alignment layer having an alignment direction;
- and
- drying and polymerizing the mixture of the liquid crystal monomers and the surface-modified nanoparticles;
- wherein the polymerized liquid crystal monomers have an axis of alignment along the alignment direction of the alignment layer, and the plurality of first ligands induce parallel alignment of long axes of the plurality of nanoparticles relative to the axis of alignment of the polymerized liquid crystal monomers.
