Patent

CA 2648956

The invention relates to a method for producing inverse opals having adjustable channel diameters. For this purpose, solid organic or inorganic template spheres are partially fused. The invention especially relates to a method for thermally fusing PMMA templates having a submicron size at a maximum temperature of 160°C during a maximum period of 60 minutes. The method according to the invention allows adjustment of the cavities to diameters ranging from 100 to 700 nm.

L'invention concerne un procédé de réalisation d'opales inverses à diamètres de canaux réglables. Selon l'invention, des billes matricielles organiques ou minérales massives sont en partie fondues. L'invention concerne en particulier un procédé de fusion thermique de matrices PMMA submicrométriques à une température maximale de 160° C pendant 60 minutes au maximum pour réaliser des cavités dont le diamètre peut être réglé entre 100 et 700 nm.
