Title: MANUFACTURE METHOD OF NANOMATERIAL WITH ANTIBACTERIAL PROPERTIES, THE MATERIAL THEREOF, AND ITS USE
Abstract:
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.
