Liquid crystal alignment with a molecular template of imprinted polymer layer during phase separation
نویسندگان
چکیده
We developed a liquid crystal LC alignment method using a molecular template of an imprinted polymer layer during polymerization-induced phase separation. Our results showed that the nematic ordering of LC is transferred to the polymer chain ordering during an anisotropic phase separation, which produces an anisotropic azimuthal surface anchoring. Using in-plane field treatment during phase separation, a twisted nematic cell is demonstrated. © 2006 American Institute of Physics. DOI: 10.1063/1.2184891

متن کاملEffect of polymer structures on electro-optical properties of polymer stabilized liquid crystal films
The polymer stabilized liquid crystal (PSLC) film is a relatively novel electro-optical material, which is generally obtained by dissolving a small amount of a bifunctional photoreactive monomer in a low molecular mass liquid crystal. In this paper, the PSLC films were prepared with photoreactive biphenyl methacrylate monomers by photopolymerization induced phase separation. The effects of liqu...
