Download or read book Cellulose Nanocrystal written by Soon Yee Liew and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the use of cellulose nanocrystals for the fabrication of porous nanocomposites with electronic conducting polymers for electrochemical supercapacitor applications. The exceptional strength and negatively charged surface functionalities on cellulose nanocrystals are utilised in these nanocomposites. The negatively charged surface functionalities on cellulose nanocrystals allow their simultaneous incorporation into electropolymerised, positively charged conducting polymer for charge balancing, i.e. co-electrodeposition occurs. The exception is the case of polyaniline-cellulose nanocomposites which formed with uncharged cellulose nanocrystals. As a result, the cellulose nanocrystals form the structural backbone of the nanocomposites in which the mechanical integrity of the nanocomposites becomes significantly improved. In Chapter 1, supercapacitors and the electrode materials are introduced. The equations relating to the characterisation of supercapacitor materials and devices are also introduced in Chapter 1. In the first half of Chapter 2, the basics of electrochemistry and electrochemical methods used in this work are discussed. In the second half, the preparation of the cellulose nanocrystals is reported. Chapters 3 and 4 report the fabrication and characterisation of polypyrrole-cellulose nanocrystal composites with respect to their capacitance, stability and charging characteristics. Chapter 5 discusses the making of the polypyrrole-cellulose nanocomposites at a practical scale for supercapacitors, and consequently reports the making and testing of a laboratory prototype supercapacitor. Chapter 6 extends the PPy work to other ECPs by the fabrication and characterisation of polyaniline and poly(3,4-ethylenedioxythiophene) nanocomposites with cellulose nanocrystals. Finally, Chapter 7 contains the closing conclusions that I have made for this thesis, and in Chapter 8, I have made some suggestions for future work in this area. In this project, the materials were characterised using mainly scanning electron microscopy and a range of electrochemical techniques. Specifically, the performance of the polypyrrole-cellulose nanocomposites was compared against that of polypyrrole-carbon nanotube nanocomposites, current state-of-the-art materials for supercapacitor. The performance of all the nanocomposites described in this thesis was also critically compared against that of the best available similar materials in literature, to assess the viability of these materials for applications in supercapacitor devices. Significantly, to the best of my knowledge, this is the first time that the nanocomposites of electronic conducting polymers with non-conducting rod-like nanoparticles fabricated using the co-electrodeposition method were described. The performance of conducting polymer composites was significantly enhanced by the presence of the cellulose nanocrystals as the backbone. This work also proves, for the first time, that conducting polymer composite containing non-conducting nanofillers can also achieve high performance. This is a very interesting finding, compared to previous work reported in the literature for similar materials, such as those developed using carbon nanotubes as the composite filler.

Download or read book Electrochemical Supercapacitors written by B. E. Conway and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first model for the distribution of ions near the surface of a metal electrode was devised by Helmholtz in 1874. He envisaged two parallel sheets of charges of opposite sign located one on the metal surface and the other on the solution side, a few nanometers away, exactly as in the case of a parallel plate capacitor. The rigidity of such a model was allowed for by Gouy and Chapman inde pendently, by considering that ions in solution are subject to thermal motion so that their distribution from the metal surface turns out diffuse. Stern recognized that ions in solution do not behave as point charges as in the Gouy-Chapman treatment, and let the center of the ion charges reside at some distance from the metal surface while the distribution was still governed by the Gouy-Chapman view. Finally, in 1947, D. C. Grahame transferred the knowledge of the struc ture of electrolyte solutions into the model of a metal/solution interface, by en visaging different planes of closest approach to the electrode surface depending on whether an ion is solvated or interacts directly with the solid wall. Thus, the Gouy-Chapman-Stern-Grahame model of the so-called electrical double layer was born, a model that is still qualitatively accepted, although theoreti cians have introduced a number of new parameters of which people were not aware 50 years ago.

This book was released on 2024-01-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers are extended chain giant organic molecules which consists of repeated interlinking of many monomer units in long chain there by given its name poly, meaning 'many' and mer, meaning 'part' in Greek. A polymer is similar to a necklace made from numerous tiny beads joining together known as monomers. The nonconducting properties of most of the polymers signify a substantial advantage for various practical applications of plastics. However, organic polymers with good electrical conductivity have been observed during last two decades. The polymeric materials have good processability, less specific weight, corrosion resistance and also the exciting prospects for plastics fabricated in to films, electronic devices and electrical wires. Because of these properties, in recent years they have grabbed the attention of both academic researchers and industrial domains ranging from solid state physics to chemistry and to electrochemistry. Conducting polymers are the class of polymers which can conduct electricity due to its T-electron system. Sometimes these conducting polymers are also called organic polymeric conductors or conjugated polymers or purely conductive polymers. The existence of alternate single and double bonds between the carbon atoms leading to formation of sigma (a) and pi (T) bonds is known as conjugation. Due to the formation of covalent bonds between the carbon atoms the a-electrons are fixed and immobile, while the remaining T-electrons are easily delocalized upon doping. Thus, an extended T system along the conducting polymer backbone confers the electronic conduction due to the movement of T-electrons along the chain. Ever since the invention of iodine doped conductive polyacetylene, a new field of conducting polymers, which is also called as "synthetic metals", with a number of different conducting polymers and their derivatives have been established.
