PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

Organosilicones
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.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : This study focuses on the vacuum-free deposition of nano-organosilicon coating through cyclonic plasma deposition on polymeric separators for application in lithium-ion batteries. Optical emission spectroscopy was used to determine various chemical plasma species and the association of the cyclonic plasma deposition of nano-organosilicon coating. The surface detections by ATR-FTIR and XPS revealed that the plasma power is the main reason affecting nano-organosilicon coating from organic to more inorganic features. The cyclonic-plasma-deposited nano-organosilicon coating was applied to the surface of a polymeric lithium-ion battery separator. The surface characteristics of the altered separator were analyzed through ATR-FTIR, TGA, EIS, and uptake test. The results indicated that the deposition of the nano-organosilicon coating on the separator surface improved the heat resistance and electrochemical performance of the polymeric separator. The synergistic effect of the cyclonic-plasma-coated separator was observed; that is, the electrolyte uptake of the cyclonic-plasma-coated separators was larger than that of a commercial separator.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Phytic acid (PA)-coated zinc oxide (ZnO) nanoparticles were developed to produce high-efficiency flame-retarding (FR) additives for coating formulations. These hybrid (organic/inorganic) additives were fabricated using a layer-by-layer (LBL) approach to harness the FR properties of PA and ZnO on a single-platform nanoscale scaffold. These nanoparticles can be uniformly dispersed in a polyurethane (PU) coating for applications on metal substrates. The incorporation of the PA/ZnO layer-by-layer nanoparticles at 20 wt% of the polymeric resin did not adversely affect the physico-mechanical properties of the coatings. Flame-retardant properties of PU samples containing nanomaterials, showed a 50% reduction in flame spread rate than that observed from the samples prepared with only ZnO nanoparticles. Cone calorimeter studies performed on the metal panels coated with 20 wt% PA/ZnO nanoparticles-infused PU resins showed a 25% reduction in peak heat release rate and a 50% reduction in total heat release (THR) compared to control coatings prepared without nanoparticles. Scanning electron microscopy images revealed the presence of bubble-like morphologies in the burnt samples containing the nanoparticles, indicating char formation and obstruction of escaping gases produced during the burning of the coating materials. This study clearly reveals that the coatings prepared with PA/ZnO hybrid nanoparticles can protect metal substrates against fire-related damage.

Silane-anilineIndex. décimale : 667.9 Revêtements et enduits Résumé : Synthesis of polyaniline on functionalized TiO2 using two-container type in situ coating technique
The possibility of coating polyaniline molecules onto functionalized TiO2 particles was explored using two-container type in situ coating technique. The TiO2 particles were functionalized by silane–aniline molecules as linker between the TiO2 and polyaniline molecules. The precursor and oxidizing agent were placed in two separate containers during polymerization to minimize aggregation of polyaniline molecules in the bulk of the solution. Peaks detected from the infrared spectra possess the vibrational peaks associated with the synthesized polyaniline molecules coating onto the silane–aniline functionalized TiO2. A possible configuration was constructed to illustrate the coexistence of different structures as a result of the synthesized polyaniline molecules onto the functionalized TiO2 surface. Morphology of the samples using SEM with EDX mapping shows the uniform distribution of Ti and Si atoms throughout the sample. By utilizing the two-container type in situ coating technique, polyaniline molecules were successfully coated onto the surface of TiO2 particles using silane–aniline as coupling agent.Note de contenu : - Table 1 Peaks obtained from (a) silane–aniline functionalized TiO2 and (b) polyaniline-coated silane–aniline functionalized TiO2 with respect to TiO2 using FTIR DOI : https://doi.org/10.1007/s11998-021-00562-1 En ligne : https://link.springer.com/content/pdf/10.1007/s11998-021-00562-1.pdf Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=38080

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Partial incorporation of bio-based diol in the synthesis of UV-curable polyurethane dispersion (PUDs) has been studied. The bio-based diol was synthesized from vanillin. Divanillin (DV) was used as a partial replacement for polyethylene glycol an industrial diol. PUDs were synthesized by reacting vanillin and polyethylene glycol in different percentages (10:90, 30:70, and 50:50) with isophorone diisocyanate along with 2-dimethyl propionic acid. Hydroxyethyl methacrylate is attached to incorporate unsaturation, which helps in the UV curing process, and triethyl amine is used for acid group neutralization. The synthesis of DV and resin was confirmed by FTIR spectroscopy. Divanillin synthesis confirmation was carried out by NMR spectroscopy. The synthesized resin was dispersed in water and applied on a wooden panel. Mechanical testing, like scratch resistance, pencil hardness, and cross-hatch adhesion tests, was carried out on the cured coatings to determine their properties. The 30% incorporation of DV shows the highest pencil hardness (2H) and scratch hardness (0.90 kg) among all the DV formulations and the results were comparable to plain formulation. The 30% DV also exhibits good gloss at 60° angle with value of 76.7. Coatings exhibited excellent acid resistance and moderate resistance towards alkalis. TGA was performed on the plain PU and 30% DV and the onset temperatures were 190 °C and 185 °C, respectively. All the dispersions formed were tested to determine their particle size, and the particle size distributions were in the range of 3–55 µm. Gel content percentages for all the samples were in the range of 90–97%.
