Book Synopsis Thermotropic Liquid Crystal Polymers by : Tai-Shung Chung
Download or read book Thermotropic Liquid Crystal Polymers written by Tai-Shung Chung and published by CRC Press. This book was released on 2001-03-01 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid crystal polymers are sometimes called super polymers--with good reason. Their wide range of exceptional properties and ease of processing make them design candidates for many demanding applications. This new book provides a thorough review of LCP technology with the emphasis on the chemistry, synthesis and characterization of the material in its many variants. Additional chapters cover processing and applications. From the Editor's Preface The field of thermotropic liquid crystalline polymers has grown substantially in the last two decades, with fundamental research, publications, commercial products, and patents. In the 1980's, Dr. Ralph Miano led my colleagues and me at Hoechst Celanese in commercializing the first thermotropic liquid crystalline polymers, based on Dr. Gordon Calundann's composition patents. Today, more than seven companies have produced thermotropic liquid crystalline polymer materials, with at least 50 variants available. Hence, it is timely to compile a comprehensive review on the nature of this type of material and the ongoing progress in this field.... The goals of this book are to summarize previous work, provide new insights into this class of polymers, and add to the understanding of the formation of liquid crystallinity. This book covers a wide range of topics and addresses different disciplines in the field. The chapters are arranged as a learning scheme for the professional, from basic science to applied engineering. The first few chapters summarize the syntheses of various polyester, polyester-amid, and polyimide liquid crystalline polymers. The science and origins of liquid crystal formation are revealed. Next, we introduce the characterizations of these materials by their different chemical and physical aspects. Because most commercially available thermotropic liquid crystalline polymers have been used in the form of composites, we have also incorporated a chapter on polymer blends, detailing blending mechanisms and resultant properties. Two chapters on thermosetting liquid crystalline polymers integrate them with other topics, because of their unique importance and their applications for microelectronics and packaging. The final chapter deals with the engineering and processing aspects of thermoplastic liquid crystalline polymers for a variety of applications.
Book Synopsis Effects of Melt Viscosity Reduction of Polycarbonate by Low Molar Mass Liquid Crystal by :
Download or read book Effects of Melt Viscosity Reduction of Polycarbonate by Low Molar Mass Liquid Crystal written by and published by . This book was released on 2007 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is devoted to the investigation of the effect of the reduction in melt viscosity of Polycarbonate by low molar mass liquid crystal chemical. The simple viscoelastic model, Maxwell model, was also chosen to explain the mechanism of the reduction and investigate the rheological parameters of the system. The phase behavior of low molar mass liquid crystal (LLC) and polycarbonate blends is firstly reported. The results of small angle light scattering (SALS) indicate that the LLC is miscible in the mixture for weight fractions of LLC less than 6%. For the study of the rheological properties, mixtures of two different liquid crystals with different molecular weight of polycarbonate were prepared inside the miscible regime of the blend. Both the complex and steady shear viscosities of the blends were found to be significantly decreased upon addition of small amounts of liquid crystal. At low shear rate, the steady state shear viscosity was similar to the pure polycarbonate, whilst, at higher shear rates, three further regimes of behavior, as has been described for liquid crystals and liquid crystal polymers, were found despite the low concentration of LLC; hence, the rheological properties of the blends can be significantly modified by small concentrations of LLC (as low as 1%). The decrease in melt viscosity of polycarbonate that we observe upon addition of LLC is not due to lubrication effects at the interfaces, as shown by reproducible oscillatory shear flow sweeps. The further study the effect of LLC content on the interdiffusion property, the diffusion coefficient was obtained using Nuclear Reaction Analysis (NRA) of bilayer films. An addition of only 1wt% liquid crystal to the polycarbonate significantly increased the diffusion coefficient, but at higher concentration the converse was found. To examine the bulk mechanical property, Dynamic mechanical analysis was used for observe the glass transition temperature of the blend. The decrease in Tg with liquid crystal content was found, in all cases the presence of single Tg indicates that blends are miscible.

Book Synopsis Thermotropic Liquid Crystal Polymer Blends by : Francesco Paolo La Mantia
Download or read book Thermotropic Liquid Crystal Polymer Blends written by Francesco Paolo La Mantia and published by CRC Press. This book was released on 1993-12-04 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, studies by both industry and academic researchers have opened the door to improving performance and reducing costs of these new materials. The particular structure and morphology of LCPs, as well as their peculiar rheological behavior, have stimulated researchers to develop new theoretical models and new characterization and processing techniques to more fully understand and utilize LCPs. Although the scientific literature is very rich in data on the synthetic techniques and on the relations between structure and phase behavior of these new polymers, the understanding of the rheological and processing aspects is still far from satisfactory-particularly in the case of LCP blends. In fact, although an appreciable number of patents and scientific papers have appeared describing the phase behavior, the rheology, and the mechanical properties of many of these polyblends, several aspects of the relations between processing and morphology, and between morphology and properties of these materials are still obscure or even controversial. Now, this new book, written by leading researchers, provides an up-to-date guide and reference to the processing, rheology and applications of pure LCPs and LCP blends. The book concisely reviews the synthetic procedures for the production of LCPs and discusses the rheological behavior and processing methods. Plus, the book examines present and future applications areas of LCPs and LCP blends.
