Abstract

L'invention concerne un miroir électrochimique comportant une première électrode transparente (106) et une seconde électrode (110). Une solution électrolytique (112), disposée entre lesdites électrodes, contient des ions (116) d'un métal pouvant être appliqué par électrodéposition sur les électrodes. Sous l'effet d'un potentiel électrique négatif (118) appliqué sur la première électrode, le métal appliqué se dissout et passe de la seconde électrode à la solution électrolytique. Ce métal est ensuite appliqué par électrodéposition depuis ladite solution à la première électrode, ce qui influe sur le pouvoir du miroir à réfléchir un rayonnement électromagnétique (122). Une couche de modification de surface (108) appliquée sur la première électrode garantit une électrodéposition sensiblement uniforme, ce qui permet d'obtenir une couche de miroir qui augmente le pouvoir réfléchissant du miroir. Sous l'effet d'un potentiel électrique positif (118) appliqué sur la première électrode, le métal appliqué se dissout depuis la première électrode, puis il est appliqué par électrodéposition depuis ladite solution à la seconde électrode, ce qui diminue le pouvoir réfléchissant du miroir.
