Texto completo da fonteConcernant le système PU/EG, une faible modification du processus de carbonisation naturelle du PU est observée. La caractérisation du processus de carbonisation, menée selon une approche physique met en évidence une aptitude à la déformation de la structure carbonée formée par dégradation du revêtement PU/APP. Aucours d'un incendie, cette structure va donc se déformer plutôt que de se fissurer et ainsi permettre un maintien des performances RF. Dans le cas du système PU/EG, l'épaisseur importante, la faible densité et, comme il est possible de le supposer la faible conductivité thermique du bouclier intumescent permettent de comprendre le mode d'action de l'EG

Texto completo da fonteThe multitude of communicating systems operating at high frequencies associated to the evolution of flexible electronics have increased the interest in developing and studying soft polymers as light and low cost dielectric substrates for patch antenna. Nevertheless, due to their high loss at high frequencies, simple polymers hinder the final performances of the antenna. Regarding to that aspect, the main objective of the PhD project is to develop soft styrenic thermoplastic blends as substrates for patch antenna in the X-band. The main interest of the blends is that the final properties such as the dielectric and the mechanical ones can be tuned. Hence, the choice of the formulations of the thermoplastic blends based on styrenic copolymers was driven by the quest of a compromise between dielectric loss and softness. For the new soft developed substrates, a broadband dielectric characterization methodology has been established. The influence of the blends composition on the dielectric properties has been studied. The dielectric characteristics of the thermoplastic blends proved their potential as substrates for antenna operating at microwave frequencies. Consequently, the antenna fabrication protocol has been presented and the performances of antennas based on different blends have been analyzed and compared to literature

Texto completo da fonteThe main challenge of this work was the production of electronic circuits on injected 3Dshaped polymer components, called MIDs, by microcontact printing (μCP). μCP is a substance (chemical or biological) localisation technique through mechanical contact between a patterned stamp and a substrate. It enables the MIDs’ conductor tracks to be located using two techniques: passive μCP and active μCP. The first method involves locally depositing a thiol by μCP on the substrate’s surface, which has previously been coated with a thin metallic film. The thiol protects the metallic tracks, which must be preserved after wet chemical etching. Regarding the second method, a catalyst (palladium) is deposited by μCP, followed by the electroless metallization of the tracks. The 3D μCP issue was studied using a stamp, which matched the shape of the substrate. Our experimental results combined with finite element simulations of stamp deformation during compression and whilst in contact with the substrate, revealed the key parameters of the process: stamp/substrate alignment, contact control and stamp manufacturing. We found that the alignment tolerance was around 100μm for a 250μm thickness structured design. A stamp with a rigid support covered in a structured thin film minimises deformation during compression. Thanks to the lessons learned, we carried out our first circuits using μCP with a new machine, which was developed in the laboratory. We also addressed the problem of thickening adhesive copper layers on LCP components, as a thickening procedure had already been validated

Texto completo da fonteOn many products and structures, the painting ensures surface protection and provides aesthetic of final product. However, the new guidelines to reduce the main release's sources of Volatile Organic Compounds (VOCs) incite the industrials to use alternative to usual solvent-based paints such as powder coatings. In the case of non-conductive and heat-sensitive substrate, this substitution involves the development of new processes and the optimization of their parameters.This thesis is about controlling adhesion and understanding the adhesion of powder coatings on organic matrix composites substrates, on a physico-chemical point of view. Our work focus on a powder coating and two substrates, one containing thermosetting resin (epoxy) and the other a thermoplastic resin (PEEK) .As a first step, we analyzed the influence of the characteristic of the process on the epoxy substrate/coating interface to determine which one promotes the best adhesion between the "in mold-coating" and direct application. Then we studied the durability of these coated systems in a hydrothermal aging. Finally, we studied the effect of atmospheric plasma treatment and low pressure plasma treatment on the adhesion between powder coating and PEEK matrix substrate

Texto completo da fonteTissue engineering represents a potential approach to improve cartilage mending, where an artificial 3D extracellular matrix (ECM) is essential to generate new tissues. Native ECMs can be effectively mimicked by electrospun nanofiber membranes, specially using natural sourced polymers.In this work, chitosan (CS)-based systems (CS and CS/Hyaluronan (HA)) are transformed, by electrospinning, into biocompatible and biodegradable nanofibrous mats adapted for chondrocyte (CHCT) development. CS materials are claimed to favor cell adhesion and growth, providing the microenvironment adequate for CHCT phenotype preservation. No current procedures for cartilage renovation have successfully achieved long-lasting cartilage regeneration.Homogeneous CS, HA, and CS/HA polyelectrolyte complex solutions are prepared using formic acid mixtures as solvent. Stability of the complex is improved by thermal treatment at 120°C. After treatment, material crystallization and amide bond formation are related to modifications of physicochemical properties.Enabling electrospinning, polyethylene oxide (PEO) is incorporated to the CS and HA solutions. The PEO content in the blend is set at 30 % and electrospun CS/PEO and CS/HA/PEO fibers are obtained, with diameters ranging between 100-200 nm. Several collector types allow the production of nanofibrous mats with a visible fiber arrangement depending on the collector structure. Patterned fiber mats are produced and applied for CHCT culture and cell morphology observation.Atomic force microscopy measurements between single CHCT and CS film and fibers, help to compare adhesion strength as a function of substrate topography. The cell-substrate adhesive force is found slightly higher in the case of CS film compared to the mat. Nevertheless, adhesion is more efficient on the mats, considering a lower effective contact area (support porosity ~40%).For cell culture, the importance of CS fiber stabilization is highlighted. Cell proliferation tests, performed on CS fiber mats, revealed that fiber mats lead to higher proliferation rates compared to casted films.Topography of electrospun CS nanofiber membranes could impact cell colonization patterns. Cell alignment in certain zones of aligned fiber samples is detected. In the same way, concentration of cells is observed on zones of the mat more fiber densely charged.When comparing CHCT development on CS and CS/HA substrates, it is found that cell confluency is achieved earlier on CS/HA than on CS fibers. Cell development could be improved by the presence of HA in the support, as a natural component of the ECM, favoring cell adhesion. In both cases, high CHCT viability (>90%) is detected.Regarding cell morphology, primary CHCT maintain an oval shape in cartilage. This form is also observed for CHCT on CS and CS/HA fibrous mats. On the contrary, cells spread during monolayer cultures on flat surfaces such as films and Petri dish. Morphology preservation could indicate native cell characteristics maintaining.As an alternative for cell/substrate implantation, the feasibility of intra-articular injections of cell/fiber suspensions is studied. Proliferation profiles differ significatively from CS fiber mats, mainly attributed to the limited available surface for cell development on the fiber suspension in contrast with the continuous mat. However, since some patients do not fit for surgery, the injectable approach could become a viable treatment for cartilage regeneration.In conclusion, electrospinning process optimization and material characterization allowed the use of stable nanofiber mats for CHCT development in pursuit of tissue repair applications. Compatibility of CS-based fiber mats is confirmed and substrate efficiency compared as a function of material topography.Considering the promising results herein obtained, CS and CS/HA nanofibrous mats can be considered as potential scaffolds maintaining adequate proliferation profiles and native cell shape
