A multilayer film article is disclosed. The multilayer film article includes an infrared light reflecting multilayer film having alternating layers of a first polymer type and a second polymer type, an infrared light absorbing nanoparticle layer including a plurality of metal oxide nanoparticles dispersed in a cured polymeric binder and having a thickness in a range from 1 to 20 micrometers. The nanoparticle layer being disposed adjacent the multilayer film. The metal oxide nanoparticles include tin oxide or doped tin oxide.
L'invention concerne un article comportant un film multicouche. Cet article comprend un film multicouche réfléchissant la lumière infrarouge. Ce film présente des couches alternées d'un premier type de polymère et d'un second type de polymère, une couche de nanoparticules absorbant la lumière infrarouge comprenant une pluralité de nanoparticules d'oxyde métallique dispersées dans un liant polymère durci et présentant une épaisseur comprise entre 1 et 20 micromètres. La couche de nanoparticules est adjacente au film multicouche. Les nanoparticules d'oxyde métallique contiennent de l'oxyde d'étain ou de l'oxyde d'étain dopé.
