Title (EN) MANUFACTURE METHOD OF NANOMATERIAL WITH ANTIBACTERIAL PROPERTIES, THE MATERIAL THEREOF, AND ITS USE
(FR) PROCÉDÉ DE FABRICATION D'UN NANOMATÉRIAU AYANT DES PROPRIÉTÉS ANTIBACTÉRIENNES, MATÉRIAU À BASE DE CELUI-CI, ET SON UTILISATION
Abstract:
(EN) Method for manufacture of a nanocomposite material with antibacterial properties comprising mixing of a polymer and a filler, while the amount of the filler in the mixture is max 10% wt, and the polymer is selected from polyamide, acrylics, butadiene, dialkylphtalate, dimethylsiloxanes, isoprene, isobutylene, styrene structural units and the filler is hydrophobic carbon quantum dots hCQD which are prepared by bottom-up condensation reaction of polyoxyethylene-polyoxypropylene-polyoxyethylene. Nanocomposite material is adapted to cause an oxidative stress and reduce viability of bacteria, while the controlled antibacterial activity is activated after its illumination with blue light in the visible region having a wavelength of 420 - 470 nm.
(FR) L'invention concerne un procédé de fabrication d'un matériau nanocomposite ayant des propriétés antibactériennes, comprenant le mélange d'un polymère et d'une charge, la quantité de la charge dans le mélange étant au maximum de 10 % en poids, et le polymère étant choisi parmi le polyamide, les acryliques, le butadiène, le dialkylphtalate, les diméthylsiloxanes, l'isoprène, l'isobutylène, les unités structurelles de styrène et la charge étant composée de points quantiques de carbone hydrophobes hCQD qui sont préparés par réaction de condensation ascendante de polyoxyéthylène-polyoxypropylène-polyoxyéthylène. Le matériau nanocomposite est conçu pour provoquer un stress oxydatif et réduire la viabilité des bactéries, tandis que l'activité antibactérienne contrôlée est activée après son éclairage avec une lumière bleue dans la région visible avec une longueur d'onde de 420 à 470 nm.
