Abstract

L'invention concerne un nouveau matériau multicouche comprenant un support (10) recouvert d'une couche à mémoire de forme (20) dont un paramètre de rugosité de surface est : • supérieur à une première valeur de rugosité lorsque la température (T) est inférieure à une température seuil (Ts), et • inférieur à une deuxième valeur de rugosité lorsque la température est supérieure à la température seuil (Ts), la deuxième valeur étant inférieure à la première valeur. La couche de matériau à mémoire de forme peut être recouverte d'une couche absorbante, par exemple une couche d'un matériau thermochrome à fort coefficient d'absorption tel qu'un oxyde de Vanadium, et / ou d'une couche de matériau antireflet. Application à la réalisation de panneaux solaires thermiquesThe invention relates to a new multilayer material comprising a support (10) covered with a shape memory layer (20) whose surface roughness parameter is: • greater than a first roughness value when the temperature (T) is less than a threshold temperature (Ts), and • less than a second roughness value when the temperature is greater than the threshold temperature (Ts), the second value being less than the first value. The layer of shape memory material may be covered with an absorbent layer, for example a layer of a thermochromic material with a high absorption coefficient such as a vanadium oxide, and / or a layer of antireflection material. . Application to the production of thermal solar panels
