Book Synopsis Advanced Applications of Ionic Liquids by : Jamal Akhter Siddique
Download or read book Advanced Applications of Ionic Liquids written by Jamal Akhter Siddique and published by Elsevier. This book was released on 2022-11-02 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced Applications of Ionic Liquids discusses the intersection of nanotechnology with ionic liquids (ILs) and materials, along with opportunities for advanced engineering applications in various research fields. Novel materials at nano scales with ILs creates an upsurge in the thermal and electrochemical constancy of the nano scale particles, making them ideal for industrial applications. The implementation of ILs at nano scale includes an interaction of constituents, which is beneficial for electron transfer reactions. These new composites can be implemented as sensors, electronics, catalysts and photonics. Including ILs in polymer composites enhance electrochemical consistency, govern particle size, upsurge conductivity, reduce toxicity, and more. This book is a comprehensive reference for researchers working with IL based technologies for environmental and energy applications. - Covers all industrial aspects and advanced applications of ionic liquids (ILs) - Discusses the advanced applications of ILs across multiple fields, including industrial chemistry and chemical engineering - Includes a discussion of the use of ionic liquids in functional polymers, with applications for catalysis, energy conservation, sensors, and more

Available in PDF, EPUB and Kindle. Book excerpt: With this collection of short review papers we would like to present a broad overview of research on poly?uorenes and related heteroanalogues over the last two decades. The collection begins with papers on the synthesis of po- ?uorenesandrelatedpolyheteroarenes, thenreportsphotophysicalproperties of this class of conjugated polymers both at the ensemble and the single chain level, continues with a discussion of the rich solid state structures of poly?uorenes, and ?nally switches to device applications (e.g. in OLEDs). In addition, two chapters are devoted to de?ned oligo?uorenesas lowmolecular weight model systems forpoly?uorenes and also to degradation studies. We feel that this up-to-date collection will be very helpful to all polymer chemists and physicists, and will also aid graduate students interested in this fascinating and still growing area of research, since such a compact overview is only now available. All articles are presented by leading scientists in their ?elds, insuring state-of-the-art coverage of all relevant aspects. Together with the body of references this volume is meant to assist researchers in the daily lab routine. Moreover, Advances in Polymer Science, as an established series of high quality review papers, represents a very appropriate platform for our project.Wehopethatthisshortcollectionwillbeofgreatvaluebothforbeg- ners and established researchscientists inthe?eldofpoly?uorene research.

This book was released on 1986 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Side chain liquid crystalline polysiloxanes were synthesized by the hydrosilation of poly(methylhydrosiloxane) with p-(1-undecenyl-11-oxy) benzyl ethers of: 4-cyanophenol (IM), 4-methoxyphenol (IIM), 4-cyano-4'-hydroxybiphenyl (IIIM), 4-methoxy-4'-hydroxybiphenyl (IVM) and 2-cyano-6-hydroxynaphthalene (VM). The phase behavior of both monomeric and polymeric liquid crystals was characterized by differential scanning calorimetry and optical polarization microscopy. IM is a monotropic liquid crystal, IIM is crystalline, IIIM and IVM are enantiotropic liquid crystals, while VM presents two virtual liquid crystalline transitions and crystalline polymorphism. All the synthesized polysiloxanes present enantiotropic smectic mesomorphism.

Synthesis and Characterization of Binary Copolymers of 11- (4-Cyano-4'-biphenyl) Oxy)undecanyl Vinyl Ether with N-Butyl Vinyl Ether and of 2-(4-Cyano-4'biphenyl)oxy)ethyl Vinyl Ether with N-Butyl Vinyl Ether written by and published by . This book was released on 1992 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Copolymerization represents the simplest synthetic technique which can be used to tailor make phase transitions of both main chain and side chain liquid crystalline polymers. Indeed, copolymerization was frequently employed to manipulate the phase transitions of side chain liquid crystalline polymers. However, most of the results reported in the literature can be considered only in a qualitative way, since there are only very few cases in which information about both copolymer composition and molecular weight are available. A general classification of side chain liquid crystalline copolymers was recently discussed in a review article. There are two main classes of side chain liquid crystalline copolymers. The first one refers to copolymers containing pairs of structural units with and without mesogenic units. The second class refers to copolymers based on pairs of structural units containing mesogenic units in each structural unit.

This book was released on 1992 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis and characterization of poly(11-(4-cyano-4'-biphenyl) oxy)undecanyl vinyl ether-co-(2S,3S)-(+)-2-chloro-3-methylpentyl 4'-(8- vinyloxyoctyloxy)biphenyl-4-carboxylate)X/Y (poly(6-11)-co-(15-8)X/Y) (where X/Y represents the molar ratio of the two structural units) and poly(2S,3S)-(+)-2- chloro-3-methylpentyl 4'-(8-vinyloxyoctyloxy)biphenyl-4-carboxylate-co-3((4- cyano-4'-biphenyl)oxy)propyl vinyl ether)X/Y (poly(15-8)-co-(6-3))X/Y) with degree of polymerization of about 20 and molecular weight distribution of about 1.1 are described. The mesomorphic behavior of all copolymers determined from both first, second and subsequent differential scanning calorimetric (DSC) scans was discussed as a function of composition. As determined from the second DSC scans, poly(6-11) exhibits enantiotropic smectic A and sX (unidentified smectic), poly(6-3) enantiotropic nematic mesophases, while poly(15-8) exhibits enantiotropic sA, chiral smectic C and sX (unidentified smectic) mesophases. Poly(6-11)-co-(15-8)X/Y exhibit a sA phase over the entire range of compositions. This mesophase displays a continuous dependence of copolymer composition with an upward curvature. Poly(15-8)-co-(6-3)X/Y from 10/0 to 3/7 displays an enantiotropic sA mesophase as their highest phase, while those with X/Y from 2/8 to 1/9 an enantiotropic cholesteric mesophase.

Synthesis and Characterization of Poly(2-(4-Biphenyloxy) Ethyl Vinyl Etherby written by and published by . This book was released on 1992 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis and living cationic polymerization of 2-(4-biphenyloxy) ethyl vinyl ether (BEVE) are described. Polymers with degrees of polymerization from 3.8 to 22.1 and narrow molecular weight distribution were synthesized and characterized by differential scanning calorometry (DSC) and thermal optical polarized microscopy. When determined from their first DSC heating scans POLY(BEVE)s exhibit only a crystalline phase over the entire range of molecular weights. When determined from the second and first cooling scans, poly(BEVE) with a degree of polymerization of 3.8 exhibits an enantiotropic smectic mesophase and a crystallization process on the heating scan, while the polymers with degrees of polymerization from 4.7 to 8.1 exhibit only an enantiotropic smectic mesophase. The polymers with higher degrees of polymerization do not exhibit any mesophase. An explanation for this behavior is provided.
