摘要:	摘要： The electro-optical properties of poly(n-vinylcarbazole) (PVK) film-based liquid crystal (LC) films are reported. Firstly, the alignment direction of a rubbed PVK film is found to successfully switch toward the rubbing direction through thermal treatment. Second, a method of particular thermally induced phase separation (TIPS) of LCs and polymers is presented. The method involves a combination of dissolution process and TIPS. Additionally, a scattering-mode light shutter having the advantages of low driving voltage, polarization-independent scattering, fast response, high contrast ratio is reported. Finally, the scattering-mode light shutter with different transmission is achieved by illuminating the cell under various light intensities. 出版者： Philadelphia: Taylor & Francis 出版日期： 2014-06-13 出處： Molecular Crystals and Liquid Crystals, 2014-06, Vol.596 (1), p.135-151 版權： Copyright © Taylor & Francis Group, LLC 2014 版權： Copyright Taylor & Francis Ltd. 2014 識別號： ISSN: 1542-1406 識別號： EISSN: 1563-5287 識別號： EISSN: 1527-1943 識別號： DOI: 10.1080/07315171.2014.918755
