Da, Silva Alexandre. "Modulation de l'émissivité infrarouge par effet électrophorétique." Electronic Thesis or Diss., CY Cergy Paris Université, 2024. http://www.theses.fr/2024CYUN1290.
Full textInfrared emissivity modulation is one of the key solutions for controlling apparent temperature, benefiting both thermal camouflage and housing thermoregulation. This modulation between high and low emissivity states can be achieved using electrophoretic displays, if they operate in specific configurations according to a given IR source and environment. Zinc oxide nanoparticles doped with various metals are used in these displays to produce infrared emissivity modulation, because of localized surface plasmon resonance. The use of microwaves and the optimization of the purification method led to a drastic reduction in synthesis time, as well as an improvement in the reproducibility of nanoparticle production. Depending on the dopant used, nanoparticles exhibit specific infrared absorbance in the two main detection ranges of infrared cameras (3-5 and 8-13 µm). The nanoparticles with aluminum, gallium and indium as dopants are then formulated into electrophoretic inks for use in similar displays. Compared with pure solvent, inks formulated at 30 mg/mL with these nanoparticles showed apparent temperature variations of around 15°C in the 3 to 5 µm range, and approximately 8°C in the 8 to 13 µm range. In an electrophoretic display equipped with asymmetrical interdigitated electrodes subjected to an electric field, the use of aluminum-doped zinc oxide nanoparticles enabled to tune the emissivity and apparent temperature of the display by more than 4°C during repeated cycles in the 8 to 13 µm range. Further experiments confirmed the transferability of the first display architecture to a flexible one with a face-to-face architecture. Consisting of a highly opened nickel grid on the front and a continuous PET-ITO counter-electrode on the back, this new architecture showed more restricted infrared switching performances, opening new optimization perspectives. Nonetheless, the use of a flexible substrate and the improved assembly made possible by such the new architecture allowed to increase the lifespan of the displays from a few weeks, to at least a year. This architecture has also enabled a significant weight reduction, dividing the total mass of the display by four

Full textAn interface between the separation technique (capillary electrophoresis) and the analytical technique (Inductively Coupled Plasma - Mass Spectrometer) was developed. In that sense, bibliographic and parametric studies allowed to define necessary conditions for the good working of both techniques. The results obtained led to the realisation of an interface capillary electrophoresis - inductively coupled plasma mass spectrometer (CE/ICP-MS). This one was experimentally validated on classical separations (alkalines /earth-alkalines and lanthanides) and the detection limit of the analytical system was determined equal to 4x10^(-11) mol. L^(-1) for plutonium. This result exhibits a gain in detection limit of a factor higher than 10^4 compared to the capillary electrophoresis in standard detection (UV). The studies were made in order to check the capacity of the CE /ICP-MS coupling as a speciation instrument for actinides at trace level and to define the associated analytical procedures. The coupling turned out to be a suited instrument for the determination of absolute electrophoretic mobilities at infinite dilution (physico-chemical property which allows to predict the migration time of an ion under an electrical field in a given electrolyte), for the determination of thermodynamic constants and for the separation of different actinide oxidation states in solution

Full textThe main objective of this thesis was to study and develop electrophoretic methods for effective charge determination of small ions, (bio)macromolecules and nanoparticles. Effective charge is a physical parameter that controls the electrostatic interactions and allows for the determination of condensed counter-ion fraction in the case of polyelectrolytes. In a first part, different models of electrophoretic mobility (Nernst-Einstein, O'Brien-White-Ohshima, Yoon-Kim) have been compared for effective charge determination from experimental values of electrophoretic mobility and hydrodynamic radius. Three other experimental methods based on the sensitivity of UV detection in indirect mode and in conductivity detection, or on the length of the isotachophoretic zones, were studied. These methods were applied to effective charge determination of dendrigraft poly-L-lysines and on drug delivery polymeric systems. A study of the ionic strength dependence of the electrophoretic mobility leads us to propose a graphical representation, called the slope-plot, allowing for the distinction between solutes according to their nature (small ions, polyelectrolytes, nanopaticles). The slop-plot can also be used for the optimization of electrophoretic separations according to the ionic strength

Full textThis work deals with the hybrid particles synthesis, using inorganic pigment for the coloured electrophoretic inks formulation. To comply with this type of application, pigments must have a sub-micrometer size, a low density and a high refractive index in order to exalt the diffusion phenomena. Blue and cyan spinel structure pigments CoAl2O4 and NiAl2O4 have been synthesized by Pechini process. In both these oxides, steric and electronic effects allowed stabilizing pure phases with enhanced colouring effects. In the case of CoAl2O4, we have to avoid the occurrence of Co3+ (LS) whereas for NiAl2O4, excess of Al3+ is necessary to get pure phases with nanosized crystallites. Then, magenta and yellow olivine structure pigments have been developed with the exploration of the solid solution LiCoxNi1-xPO4. In these compounds, the study of the electronic transitions combined with Ni2+ and Co2+ chromophores ions structure and environment in [6] site leads to comparable crystal field and so an almost similar nephelauxetic effect for both ions. Finally, the investigation of the valence state and the environment of chromium in rutile type structure Sn1-xCrxO2 allowed the synthesis of purple pigments. In a second part, the pigment surface has been modified with n-trimethoxysilane chains to improve the pigment dispersion in apolar media. Then, modified pigments have been polymerised in Isopar-G by nitroxyde mediated radical polymerisation with methyl methacrylate to decrease the hybrids density and to obtain stable inks. The impact of the experimental conditions has been studied on each pigments in order to formulate coloured and charged inks without any charge control agent. A two-colour electrophoretic device (blue/white) has been finally tested

Full textThe main objective is to realize some photo-solar absorbers by electrophoretic deposition of nanoparticles, having some tuneable optical properties. This study takes place in the field of the development of a macroscopic object through a 'bottom-up' approach. The understanding of the mechanism of the deposition is crucial to design these new materials. The nanostructure of the coatings with density gradient will be elaborated by pulsed and variable electric field, and characterized by scanning microscopy and energy dispersive X-ray and alongside a modelling of the electrophoretic phenomenons (such as the electric field drop) will be investigated. The conversion efficiency of the tandem material, which has to display a high absoptance in the solar spectrum domain (0.5-2.5 µm) whereas a low emittance in the far infra-red (2.5-20 µm), will be calculated from the reflectance spectra of the UV-vis-NIR and the Fourier transform InfraRed spectroscopy in order to link the electrophoretic parameters to the spectral selectivity
