(FR) COMPOSITION D'ENCRE, PROCÉDÉ DE FORMATION D'UN ÉLÉMENT CONDUCTEUR ET DISPOSITIF CONDUCTEUR
Abstract: front page image
(EN) According to embodiments of the present invention, an ink composition for forming a conductive film is provided. The ink composition includes a plurality of nanostructures distributed in at least two cross-sectional dimension ranges, wherein each nanostructure of the plurality of nanostructures is free of a cross-sectional dimension of more than 200 nm; preferably each nanostructure of the plurality of nanostructures is encapsulated with a surfactant. In a preferred embodiment, the nanoparticles have bimodal distributions: small particles (5 - 10 nm) and large particles (30 - 100 nm), wherein the small particles are likely to occupy the empty space between the large particles, and therefore helps in densification of the film. According to further embodiments of the present invention, a conductive member is formed by fusing the plurality of nanostructures of the ink composition to each other.
(FR) Des modes de réalisation de la présente invention concernent une composition d'encre pour former un film conducteur. La composition d'encre comprend une pluralité de nanostructures distribuées selon au moins deux plages de dimension en coupe transversale, chaque nanostructure de la pluralité de nanostructures étant exempte d'une dimension de section transversale supérieure à 200 nm ; de préférence, chaque nanostructure de la pluralité de nanostructures est encapsulée avec un tensioactif. Dans un mode de réalisation préféré, les nanoparticules ont des distributions bimodales : de petites particules (5-10 nm) et de grosses particules (30-100 nm), les petites particules étant susceptibles d'occuper l'espace vide entre les grosses particules, ce qui aide à la densification du film. Selon d'autres modes de réalisation de la présente invention, un élément conducteur est formé par fusion de la pluralité de nanostructures de la composition d'encre les unes aux autres.
