This book was released on 2016 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poly(arylene ether sulfone)s with pendent aryl iodide group was successfully synthesized via Nucleophilic aromatic polycondensation of 1-(3,5-difluorophenyl sulfonyl)-4-iodobenzene using 4,4{u2019}-difluorodiphenylsulfone (DFDPS) and Bisphenol A in the ratio 25:75:100. Iodo monomer was prepared by reacting 3,5-difluorodiphenyl sulfone with N-iodo succinimide (NIS). Using GC/MS and NMR spectroscopy, the quantitative analysis was done to this monomer. Modification was done to iodo copolymer using sodium azide and copper sulfate as catalyst to form azide copolymer. Further modification of the azide copolymer to triazole copolymers via Click Chemistry using different alkynes such as 1-octyne, phenyl acetylene, propargyl alcohol and acetylenedicarboxylic acid. Polymers characterization was done using 1H, 13C NMR, IR spectroscopy and SEC. The highest molecular weight (Mw) was found to be 19,033 Da with a PDI 3.0 for iodo copolymer and the least was found to be 6,888 with a PDI 2.5 for acetylenedicarboxylic acid derivative copolymer. Thermal analysis of polymers was done using TGA and DSC. The Td5% values were ranging from 260{u00BA} to 476{u00BA}. The highest Tg was 191{u00BA} for phenyl derivative copolymer and the least was 174{u00BA} for alkyl derivative copolymer. TGA was not ran on azide copolymer as it may contain explosive copper azide traces. IR spectroscopy was used to confirm the structures of azide copolymer, propargyl alcohol derivative and acetylenedicarboxylic acid derivative copolymers.

Percec and published by . This book was released on 1991 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous publications from our laboratory reported the synthesis and characterization of polymethacrylates, polyacrylates and poly(methylsiloxane)s containing 4-S( - )-2-methyl-l-butoxy-4'-(w-alkan-1-yloxy)-a-methylstilbene side groups, in which the alkanyl group contains two eleven methylenic units. Although in the field of low-molar-mass liquid crystals there are some empirical rules which are used to design compounds displaying chiral smectic C (sC*) mesophases, such rules are not available for side chain liquid crystalline polymers. A classic example comes from our laboratory where repeated attempts to synthesize side chain liquid crystalline polymers exhibiting a sC* mesophase led to polymers exhibiting a sA mesophase. Therefore, we decided to perform a series of systematic investigations aimed to derive some empirical rules useful for the molecular design of side chain liquid crystalline polymers exhibiting sC* mesophases.

This book was released on 2008-07-11 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of ferroelectricity is a branch of solid state physics which has shown rapid growth during the recent years. Ferroelectric materials exhibit unusual electric properties which make them useful in modern (opto)electronic technology, esp. display technology. Ferroelectric and antiferroelectric liquid crystals, including also various polymer forms, are the hottest research topic today in liquid crystals. The field is at the very beginning of industrial exploitation - a sensitive phase in which a good reference work is needed and will have a broad spectrum of readers both at universities and in industry.

Download or read book Photoalignment of Liquid Crystalline Materials written by Vladimir G. Chigrinov and published by John Wiley & Sons. This book was released on 2008-09-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoalignment possesses significant advantages in comparison with the usual ‘rubbing’ treatment of the substrates of liquid crystal display (LCD) cells as it is a non-contact method with a high resolution. A new technique recently pioneered by the authors of this book, namely the photo-induced diffusion reorientation of azodyes, does not involve any photochemical or structural transformations of the molecules. This results in photoaligning films which are robust and possess good aligning properties making them particularly suitable for the new generation of liquid crystal devices. Photoalignment of Liquid Crystalline Materials covers state-of-the-art techniques and key applications, as well as the authors’ own diffusion model for photoalignment. The book aims to stimulate new research and development in the field of liquid crystalline photoalignment and in so doing, enable the technology to be used in large scale LCD production. Key features: Provides a full examination of the mechanisms of photoalignment. Examines the properties of liquid crystals during photoalignment, with particular reference made to the effect on their chemical structure and stability. Considers the most useful photosensitive materials and preparation procedures suitable for liquid crystalline photoalignment. Presents several methods for photoalignment of liquid crystals. Compares various applications of photoalignment technology for in-cell patterned polarizers and phase retarders, transflective and micro displays, security and other liquid crystal devices. Through its interdisciplinary approach, this book is aimed at a wide range of practising electrical engineers, optical engineers, display technologists, materials scientists, physicists and chemists working on the development of liquid crystal devices. It will also appeal to researchers and graduate students taking courses on liquid crystals or display technologies. The Society for Information Display (SID) is an international society, which has the aim of encouraging the development of all aspects of the field of information display. Complementary to the aims of the society, the Wiley-SID series is intended to explain the latest developments in information display technology at a professional level. The broad scope of the series addresses all facets of information displays from technical aspects through systems and prototypes to standards and ergonomics
