Title (EN) COMPOSITE FILM, DEVICE INCLUDING, AND METHOD OF FORMING THE SAME
(FR) FILM COMPOSITE, DISPOSITIF COMPRENANT ET PROCÉDÉ DE FORMATION DE CELUI-CI
Abstract:
(EN) In present invention, various embodiments provide a photothermotropic composite film. The composite film comprises a matrix and one or more nanostructures comprising a metal oxide semiconductor which is configured to convert radiant energy to thermal energy. The matrix has a property which is changeable based on the thermal energy received by the matrix from the metal oxide semiconductor. In a preferred embodiment, hybridization of the poly(N-isopropylacrylamide) (PNIPAM) hydrogel and antimony-tin oxide (ATO) is provided as the composite film. In this film, the ATO absorbs at near-infrared (NIR) region and acts as nanoheater to induce the optical switching of the hydrogel. The behaviour of this composite film can be used as a new generation of autonomous passive smart windows for climate -adaptable solar modulation.
(FR) Dans la présente invention, divers modes de réalisation concernent un film composite photothermotrope. Le film composite comprend une matrice et une ou plusieurs nanostructures comprenant un semi-conducteur d'oxyde métallique qui est conçu pour convertir l'énergie rayonnante en énergie thermique. La matrice a une propriété qui peut être changée sur la base de l'énergie thermique reçue par la matrice à partir du semi-conducteur à oxyde métallique. Dans un mode de réalisation préféré, l'hybridation du poly (N-isopropylacrylamide) (PNIPAM) et de l'oxyde d'antimoine-étain (ATO) est fournie en tant que film composite. Dans ce film, l'ATO absorbe au niveau de la région du proche infrarouge (NIR) et sert de nanodispositif de chauffage pour induire la commutation optique de l'hydrogel. Le comportement de ce film composite peut être utilisé comme nouvelle génération de fenêtres intelligentes passives autonomes pour la modulation solaire adaptable au climat.
