Full textIn this PhD thesis, applications of lowtemperature plasmas at atmospheric pressure are discussed. In particular, bio-decontamination of planktonic bacteria and bacterial biofilms on flat and complex surfaces by air corona discharges and argon plasma. In this work, we characterize three plasma sources which are used for decontamination of Escherichia coli. DC corona discharges in air - positive streamer corona and negative Trichel pulses were used for decontamination of planktonic bacteria and bacterial biofilms. In some experiments water was electrosprayed onto samples from high voltage electrode. Bio-decontamination of bacterial biofilms was carried out on glass cover slides, within 15 min plasma treatment most of the bacteria were rendered uncultivable. Part from these uncultivable bacteria remained viable only top layers of the biofilm were killed, according to confocal laser scanning microscopy of biofilms stained by live/dead viability kit. The secondplasma source was pulsed corona discharge propagated inside the long narrow quartz tube in which dry argon or argon with water vapor was flowing at atmospheric pressure. This type of discharge has a potential application in decontamination of inner surfaces of catheters or other long tubular devices or could able to deliver low-temperature plasma on longer distances inside the human body. Firstly, this low-temperature plasma source was characterized by its electrical parameters, then, an optical emission spectroscopy of plasma identified UV B emission form excited hydroxyl radical especially with humid argon working gas. The effect of this UV B was tested on planktonic bacteria and was found out to cause up to a substantial damage even further downstream the tube. The last plasma source has argon jet which used dry, humid or water saturated argon as a working gas. This discharge was predominantly used for biofilm decontamination, where we received similar results as with DC corona discharges

Full textIntensive development of the industry in the direction of design and optimisation of novel materials and coatings leads to invention and elaboration of new powder coating technologies. One of these technologies is Cold Spray of various materials and composites. The properties of composites materials depend on their phase composition and structure of various phases. For this reason, it seems to be reasonable to manage the cold sprayed material structure by following heat treatment. Such a combined technology opens the new opportunities to control the phase comporition, dislocation and gain structure of materials. In this case, the new opportunities to obtain various phase composition and properties of materials are opened. The main goal of the work is to examine the specific features of cold spraying process of composite coatings obtained by deposition of powder mixtures or separate layers of soft and hard materials, and to define their influence on composite structure and properties in order to obtain and to develop the new composite coating applications. Three main groups of coating are studied : Al-SS coating for possible application as a thermal barrier coating, Ti-Al intermetallic coating and naw anti-frictional SS-SiC coating. Thermal tratment of the coatings is performed to favour the formation of intermetallic components and stainless steel matrix graphitisation in case of SS-SiC coatings. Mechanical properties of the coatings such as microhardness and elastic modulus are evaluated on the base of straingradient plasticity theory and the parameters of the depth dependence of the materials are calculated. Possible applications of the deposited coatings are developed and discussed

Full textFor weak treatment conditions, on model surface, the polar surface energy of the plasmapolyacetylene coating is the lowest. This coating is constituted mainly of alkyl groups, simple and double carbon-carbon bounds. CH, one of the species of the plasma phase identified by OES spectroscopy is one of the precursors of this coating. Two smectites, the montmorillonite and the Laponite, have been treated by plasma in these conditions to modify their polar surface energies and to improve their compatibilization with polyethylene. Their plasma treatments allow the coating on their external surfaces and also an alteration of their structures, lesser effect for the Laponite. Defects in the structure of the montmorillonite are observed. A beforehand lyophilised Laponite permits a grafting of the coating between the layers of this smectite. The addition of these charges modified by plasma in the molten polyethylene allows a diminution of the peak Heat Release Rate

Full textL’utilisation des plasmas dans le domaine du traitement de surface est de plus en plus répandue, en particulier pour améliorer l’adhérence d’un système revêtement-substrat. Après s’être retrouvés chez les polymères synthétiques, les traitements assistés par plasma ont fait progressivement leur apparition dans le domaine du bois afin de répondre aux besoins de l’industrie forestière qui utilise les revêtements et les adhésifs. Bien que plusieurs travaux de recherche ont pu démontrer le potentiel des plasmas pour ces industries, la physique et la chimie gouvernant l’interaction plasma-bois ainsi que son rôle sur les propriétés d’adhérence demeure embryonnaire. Ce projet de maîtrise démontre que les traitements plasmas DBD à la pression atmosphérique modifient la surface du bois selon divers mécanismes tels que le mouvement d’extractibles en surface, la fonctionnalisation chimique ainsi le greffage de radicaux libre.
