Title (EN) ADHESIVE, THE PRECURSOR OF WHICH IS APPLIED IN LIQUID FORM AND UV-POLYMERIZED, FOR ENCAPSULATING FLEXIBLE ELECTRONIC DEVICES, IMPROVING THE PROTECTION AGAINST GAS PERMEABILITY
(FR) ADHÉSIF DONT LE PRÉCURSEUR EST APPLIQUÉ SOUS FORME LIQUIDE ET POLYMÉRISÉ UV, POUR L'ENCAPSULATION DE DISPOSITIFS ÉLECTRONIQUES FLEXIBLES, AMÉLIORANT LA PROTECTION CONTRE LA PERMÉABILITÉ AUX GAZ
Abstract:
(EN) The invention relates to a process for encapsulating a flexible electronic device with at least one flexible sheet that protects against orthogonal gas permeation, by means of an adhesive that protects against lateral gas permeation, the process comprising: a step of applying a layer of a polymerizable precursor of the adhesive that protects against lateral gas permeation, to the surface of the device and/or to the surface of the flexible gas-protection sheet, comprising oligomers with reactive double bonds of (meth)acrylic, vinyl, allyl or unsaturated polyester type, and preferably of (meth)acrylic type and a polymerization initiator, a step of polymerizing the acrylic precursor applied, when it is positioned between the device and the gas-protection sheet, in order to form the adhesive that attaches the protective sheet to the device while protecting this device from lateral gas permeation.
(FR) L'invention concerne un procédé d' encapsulation d'un dispositif électronique flexible avec au moins une feuille flexible de protection contre la perméation orthogonale aux gaz, par l'intermédiaire d'un adhésif de protection contre la perméation latérale aux gaz, le procédé comprenant: une étape d'application d'une couche d'un précurseur polymérisable d'adhésif de protection contre la perméation latérale aux gaz, sur la surface du dispositif et/ou sur la surface de la feuille flexible de protection aux gaz, comprenant des oligomères à double liaisons réactives de type (méth)acryl, vinyl, allyl ou polyester insaturé, et de préférence de type (meth) acryliques et un amorceur de polymérisation une étape de polymérisation du précurseur acrylique appliqué, alors qu'il se retrouve disposé entre le dispositif et la feuille de protection aux gaz, afin de constituer l'adhésif solidarisant la feuille de protection au dispositif tout en protégeant celui-ci de la perméation latérale aux gaz.
