Ebru A. Buyuktanir has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8257639
    Abstract: A process for making a stimuli responsive liquid crystal-polymer composite fiber comprising mixing a liquid crystal, a polymer, and a solvent; processing the mixture in the presence of an electric potential across a collection distance; phase separating a polymer and said liquid crystal; and encapsulating said liquid crystal within said polymer. The fiber generally comprises a liquid crystal core and a polymer shell wherein the liquid crystal is responsive to chemical changes, thermal and mechanical effects, as well as electrical and magnetic fields. A liquid crystal containing fiber can be utilized as optical fibers, in textiles, and in optoelectronic devices.

  • Publication number: 20100279125
    Abstract: The invention provides a film comprising a polymer dispersed liquid crystal (PDLC) which exists independently from a substrate, i.e. a substrate-free PDLC; a fiber, a fabric, and a device thereof; and methods thereof. In an embodiment, a mixture comprising liquid crystal and monomers floats and is spread over a liquid base, before polymerization the mixture into a layer of polymer matrix dispersed with liquid crystal domains. The invention exhibits numerous technical merits such as improved transmittance, enhanced brightness, easier manufacturability, more flexible manufacturability, better cost-effectiveness, enhanced electro-optical performance, and improved device uniformity, among others.
