The semi-electroactive material of the invention includes a self-sustained polymer matrix in which is inserted an electroactive system including or made of: at least one electroactive organic compound capable of oxidation and/ejecting electrons and cations serving as compensation charges; or at least one electroactive organic compound capable of reduction and/or accepting electrons and cations serving as compensation charges; and ionic charges; and a liquid for solubilizing said semi-electroactive system, wherein said liquid does not solubilize the self-sustained polymer matrix, the latter being selected so as to provide a percolation path for the ionic charges, which results, upon the application of a dielectric current, in oxidation and reduction reactions of said electroactive organic compounds which are necessary for obtaining a colour contrast.
Ce matériau semi-électroactif comprend une matrice polymère autosupportée dans laquelle on a inséré un système électroactif comprenant ou constitué par: - au moins un composé organique électroactif capable de s'oxyder et/ou d'éjecter des élec-trons et des cations jouant le rôle de charges de compensation; ou - au moins un composé organique électroactif capable de se réduire et/ou d'accepter des électrons et des cations jouant le rôle de charges de compensation; et - des charges ioniques; ainsi qu'un liquide de solubilisation dudit système semi- électroactif, ledit liquide ne solubilisant pas ladite matrice polymère autosupportée, cette dernière étant choisie pour assurer un chemin de percolation des charges ioniques, ceci permettant, sous l'action d'un courant diélectrique, des réactions d'oxydation et de réduction desdits composés organiques électroactifs, lesquelles sont nécessaires pour obtenir un contraste de couleur.
