Patent

CA 2510359

The invention relates to a method for forming functional layers on an inorganic or organic substrate, characterised in that a) the inorganic or organic substrate is exposed to a low-temperature plasma, a corona discharge, an intense irradiation and/or a flame-treatment, b) 1) at least one activatable initiator or 2) at least one activatable initiator and at least one ethylenically unsaturated compound in the form of melts, solutions, suspensions or emulsions is/are applied to the inorganic or organic substrate, whereby at least one function regulating group, which regulates the desired surface characteristics of the treated substrate, is incorporated into the activatable initiator and/or the ethylenically unsaturated compound and c) the coated substrate is heated and/or irradiated with electromagnetic waves to regulate the desired surface characteristics. The invention also relates to substrates coated according to said method and to the use of said substrates.

L'invention concerne un procédé pour former des couches fonctionnelles sur un substrat inorganique ou organique. Le procédé selon l'invention est caractérisé en ce qu'il consiste : a) à soumettre le substrat inorganique ou organique à un plasma basse température, une décharge par effet couronne, un rayonnement dur et/ou à un traitement à la flamme ; à appliquer sur ce substrat inorganique ou organique 1) au moins un initiateur activable ou 2) au moins un initiateur activable et au moins un composé éthyléniquement insaturé sous forme de masses fondues, solutions, suspensions ou émulsions, et à incorporer, dans l'initiateur activable et/ou le composé éthyléniquement insaturé, au moins un groupe fonctionnel de régulation qui régule les propriétés superficielles souhaitées du substrat traité ; c) à chauffer le substrat ainsi revêtu et/ou à l'irradier au moyen d'ondes électromagnétiques, les propriétés superficielles souhaitées étant régulées. Cette invention se rapporte en outre à des substrats revêtus au moyen de ce procédé, ainsi qu'à leur utilisation.
