Title (EN) FORMATION COMPRISING AT LEAST ONE NANOFIBRE LAYER AND METHOD OF NANOFIBRE LAYER PRODUCTION
(FR) FORMATION COMPRENANT AU MOINS UNE COUCHE DE NANOFIBRES ET PROCÉDÉ DE FABRICATION D'UNE COUCHE DE NANOFIBRES
Abstract:
(EN) The invention relates to formation comprising at least one nanofibre layer. Said nanofibres have a diameter up to 600 nm produced through electrostatic spinning of polymer solution. The layer of polymer nanofibres comprises particles of photodynamic sensitizer, at the same time the nanofibres are isotropic spread in a transparent and porous layer of surface weight from 0,01 g/m2 to 15 g/m2. Next to this, the invention relates to the production method of nanofibre layer through electrostatic spinning of polymer solution in electric field created by difference of potentials between the spinning electrode and collecting electrode, while the nanofibres produced in this electric field are carried to the collecting electrode and they deposit on a surface designated to it. The polymer solution for spinning contains particles of photodynamic sensitizer, which are during spinning seized together with polymer into the nanofibres being produced, in which these particles are anchored inside or on the surface
(FR) L'invention concerne une formation comprenant au moins une couche de nanofibres ayant un diamètre allant jusqu'à 600 nm, obtenu par filage électrostatique d'une solution de polymère. La couche de nanofibres polymères comprend des particules de sensibilisateur photodynamique; en même temps, les nanofibres sont à distribution isotrope dans une couche transparente et poreuse de masse surfacique de 0,01 g/m2 to 15 g/m2. L'invention concerne également le procédé de fabrication d'une couche de nanofibres par filage électrostatique d'une solution de polymère dans un champ électrique créé par une différence de potentiel entre l'électrode de filage et l'électrode de collecte, alors que les nanofibres produites dans ce champ électrique sont transportées sur l'électrode de collecte et qu'elles se déposent sur une surface agencée sur celle-ci. La solution de polymère pour le filage contient des particules de sensibilisateur photodynamique, lesquelles sont, pendant le filage, saisies conjointement avec le polymère dans les nanofibres qui sont produites, dans lesquelles ces particules sont ancrées à l'intérieur ou sur la surface.
