Plasma à pression atmosphériqueUn plasma à pression atmosphérique (ou plasma à PA ou plasma froid) est le nom donné à une catégorie spéciale de plasma pour lequel la pression approche celle de l’atmosphère.
Le plasma à pression atmosphérique marque une nette différence avec le plasma basse et haute pression. En effet, contrairement à ces derniers aucune enceinte de traitement n'est nécessaire. Ce type de plasma peut donc être utilisé directement sur ligne de production, évitant ainsi l'utilisation de vide qui est extrêmement onéreuse.

Taille des gouttelettesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : There is a new solution on the market for the in-line inspection of the surface condition before gluing. A fine fog is sprayed and evaluated for analysis of the surface energy. This non-destructive test is performed in real time, leaves no residues and covers the entire component.

What is known as a water aerosol is produced on the surface with an ultrasound nozzle - 4. Different droplet sizes on a CFRP surface : the area on the right was treated with atmospheric pressure plasma ; here the wettability is much better and therefore the droplets are larger on average - 5. Evaluation of the droplets on a CFRP surface using the Visioncheck image processing software (a zoomed section of the original image is shown on the left, the same area after applying the droplet recognition algorithm is presented in the middle, and the evaluation of each individual drolet is shown on the right) - 6. Sample evaluation and good/bad classification of an area contaminated by a fingerprint, using automated image processing software - 7. Measurement results with evaluation of the average droplet size and wetting percentage : the diagrams on the left show the results of a plasma-activated specimen (activation Lvl1 < activation Lvl2), the diagrams on the right show the results of specimens contaminated by parting agents in various concentrations. These were tested within the scope of the ComBoNDT project (this ComBoNDT project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement no. 636494)Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28068

Surfaces -- AnalyseIndex. décimale : 667.9 Revêtements et enduits Résumé : Surface properties of a polymeric coating system have a strong influence on its performance and service life. However, the surface of a polymer coating may have different chemical, physical, and mechanical properties from the bulk. In order to monitor the coating property changes with environmental exposures from the early stages of degradation, nondestructive techniques with the ability to characterize surface properties with micro- to nanoscale spatial resolution are required. In this article, atomic force microscopy has been applied to study surface microstructure and morphological changes during degradation in polymer coatings. Additionally, the use of AFM with a controlled tip-sample environment to study nanochemical heterogeneity and the application of nanoindentation to characterize mechanical properties of coatings surfaces are demonstrated. The results obtained from these nanometer characterization techniques will provide a better understanding of the degradation mechanisms and a fundamental basis for predicting the service life of polymer coatings.

Polymérisation par transfert de chaîne réversible par addition fragmentationLa polymérisation radicalaire contrôlée par transfert de chaîne réversible par addition-fragmentation (en anglais Reversible Addition-Fragmentation Chain Transfer (RAFT)) est une technique de polymérisation radicalaire contrôlée.
Au même titre que la polymérisation radicalaire contrôlée par transfert d'atome (en anglais Atom Transfert Radical Polymerization (ATRP)) et la polymérisation radicalaire en présence de nitroxydes (en anglais Nitroxide Mediated Polymerization (NMP)), la polymérisation de type RAFT permet de synthétiser des polymères d'architecture contrôlée (polymères à blocs, étoiles, peignes, etc) de faible polydispersité et de haute fonctionnalité. Les applications de ces polymères sont, parmi d'autres, l'encapsulation de principes actifs de médicaments, la production de revêtements et peintures de nouvelles génération, la microfluidique, les tensioactifs, les adhésifs et les membranes.

The A2 + CB2 synthetic method was used where neopentyl glycol was A2 and 2,2-Bis(hydroxymethyl) propionic acid was CB2. The acid value and hydroxyl values of the synthesized hyperbranched polymer were determined according to ASTM D974 and ASTM D4274, respectively. The molecular structural characterizations of hyperbranched polyol were determined by FTIR and NMR spectroscopy techniques. The hyperbranched polyurethanes were synthesized by using hyperbranched polyol and crosslinking agent isophorone diisocyanate in different mole ratios of OH:NCO (1:1.2, 1:1.4, 1:1.6). These mixtures were used as coating materials on mild steel panels and glass plates. The coating properties of polyurethanes such as gloss and cross-cut adhesion were studied. The immersion test of coatings was carried out in HCl, NaCl, NaOH and water. The electrochemical properties of the coatings were examined using an electrochemical method in electrolytes consisting of HCl, NaOH, and NaCl. Thermal stability and surface morphology were studied by TGA and SEM, respectively.
