Available in PDF, EPUB and Kindle. Book excerpt: Plasma, the fourth state of matter, has been used for engineering applications since the early 1960s. The technology of depositing carbon- based films, popularly known as plasma polymers, is one of the applications of this technology. Plasma polymerization is an environment-friendly technology owing to its dry nature and therefore is becoming a topic of increasing interest both in the academic as well as industrial communities. Plasma polymer films have been used for surface modification of semiconductors in the electronics industry, as adhesion enhancers for metals in the automotive as well as the biomaterial industry as well as for films for gas sensing applications. However, plasma polymers have not been studied in depth for their ability to mechanically enhance the substrate as well as to protect different types of substrates. In this work, which has been segregated into three parts, plasma polymers of different monomers have been deposited on different substrates like flat porous silica and particulate matter like nanoparticles and pigments. In the first part, the films have been characterized at different deposition conditions and the mechanical properties like hardness and scratch resistance have been studied. The second part focuses on the corrosion resistance that these plasma polymers offer to the particles. In the third part, the surface modified pigments have been incorporated in novel organic coatings to study how these surface-modified pigments enhance the protective property of these coatings.

Download or read book Atmospheric Plasma Deposition of Transparent Coatings on Polymers written by Linying Cui and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric plasma enables plasma assisted coating deposition in ambient air at low temperature on large and/or complex geometry substrates. It has huge potential for coating synthesis and materials surface treatment at lower cost without the necessity of vacuum equipment, for applications of energy, display, aerospace, etc. In this dissertation, I present the results of atmospheric plasma deposition of transparent hard protective coatings on polymers. In order to deposit high quality coatings, we find that the interaction between atmospheric plasma, coating, and polymer substrate should all be optimized. Firstly, I studied the interaction between atmospheric plasma and polymer substrates. Atmospheric plasma was used to pretreat polycarbonate and stretched poly(methyl methacrylate) surfaces in order to enhance the adhesion of polymers to inorganic coatings. The treatment time and the chemical structure of the polymers were found to be important factors. For polycarbonate, a short treatment increased the adhesion energy by four times, while longer treatment resulted in low molecular-weight species formation and decreased adhesion. Next, I deposited dense silica coatings on polymers using atmospheric plasma. The coating deposition rate, molecular network structure, density, Young's modulus and adhesion to polymers exhibited a strong dependence on the precursor delivery temperature and rate, and the functionality and number of silicon atoms in the precursor molecules. The highest Young's modulus of the atmospheric plasma silica was four times higher than that of commercial sol-gel polysiloxane coatings. After that, I successfully deposited carbon-bridged hybrid organosilicate coating using atmospheric plasma, with the ethyl bridges incorporated in the silicate network under the ambient air environment. These coatings doubled the adhesion energy to polymers due to the molecular bridging effect, compared to commercial sol-gel polysiloxane coatings. Finally, I deposited a hard, adhesive, and highly transparent bilayer structure on polymers, with the bottom layer highly adhesive to polymer and the top layer hard to resist scratches. The method overcomes the challenge of fabricating coatings with high mechanical and interfacial properties in a one-step process. The bilayer structure exhibited ~ 100% transmittance in the visible wavelength range and no sacrifice of the hard or adhesive properties of the single sub-layers.

Available in PDF, EPUB and Kindle. Book excerpt: In our pioneering work, talc (magnesium silicate), mica (aluminum potassium silicate)and silica powders were coated with a thin layer of plasma polypyrrole (PPy) film in a compact RF plasma reactor. Characterization work done on the powders before and after PPy film deposition indicates that plasma polymer film deposition process alters the surface properties of the powders significantly without affecting their bulk properties. It is also shown that the PPy film coated talc and mica powders improve the mechanical strength of polypropylene matrix. Plasma surface coating of pigment particles was investigated in details using compact RF plasma reactor. Ultrafine pigment particles, Fe2O3 and Cr2O3, were coated with plasma-polymerized films using several starting monomers. The analysis of plasma polymerized coated pigments of chromic oxide and iron oxide has shown that surface coating of pigments can make a substantial difference to their behaviors. In our further work, a bench-top size tumbler RF plasma reactor that permits uniform surface modification of relatively large amounts of micron-size powdered materials is described in terms of design and construction. Scale-up to even larger batches of powdered materials seems to be feasible. Preliminary experimental data on characterization of the tumbler reactor and the plasma surface modification of micron-size polymer powders in the tumbler reactor are presented. The results show that deposition of plasma polymer film can be achieved at an appreciable rate in the tumbler reactor and plasma distribution is uniform in the action chamber. Coating of fairly large quantities of micron-size powders with a compact plasma polymer film by RF plasma polymer film deposition process can be carried out batchfully at a reasonable rate in the tumbler RF plasma reactor. The coating is uniform over the particle surface and free of pinholes. The surface properties of the micron-size powders had been altered dramatically after such a plasma polymer film deposition process. Possible reasons for the difference in deposition rate of plasma polymer film on flat substrate and powdered substrate are discussed and strategies to enhance deposition rate of plasma polymer film on powders are developed.

This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume documents the proceedings of the Symposium on Polymers in Information Storage Technology held as a part of the American Chemical Society meeting in Los Angeles, September 25-30, 1988. It should be recorded here that this symposium was cosponsored by the Division of Polymeric Materials: Science and Engineering, and the Division of Polymer Chemistry. Polymers are used for a variety of purposes in both optical and magnetic information storage technologies. For example, polymers find applications as substrate, for storing information directly, as protective coating, as lubricant, and as binder in magnetic media. In the last few years there has been a high tempo of research activity dealing with the many ramifications of polymers in the exciting arena of information storage. Concomitantly, we decided to organize this symposium and I believe this was the premier event on this topic. This symposium was conceived and organized with the following objectives in mind: (1) to bring together those actively involved (polymer chemists, polymer physicists, photochemists, surface and colloid chemists, tribo10gists and so on) in the various facets of this topic; (2) to provide a forum for discussion of latest R&D activity in this technology; (3) to provide an opportunity for cross-pollination of ideas; and (4) to identify and highlight areas, within the broad purview of this topic, which needed intensified or accelerated R&D efforts.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of invited papers (previously published in special issues of the Journal of Adhesion Science and Technology) written by internationally recognized researchers actively working in the field of plasma surface modification. It provides a current, comprehensive overview of the plasma treatment of polymers. In contrast to plasma polymerization, plasma surface modification reactions do not cause thin-film deposition, and can therefore only modify the surface properties of organic substrates. Plasma surface modifications are fast, efficient methods for improving the adhesion properties and other surface characteristics of a variety of polymeric materials. The focus of this volume is on adhesion phenomena, surface properties and the surface characterization of plasma-treated materials. This book opens with a critical review of the plasma surface modification of polymers for improved adhesion. The remainder of the papers are divided into two sections, one dealing with the characterization of plasma-treated surfaces and the second concerned with various practical applications of plasma-treated surfaces
