Smart windows can save electrical energy by controlling indoor solar penetration with adaptive modulation of optical transparency. Although conventional glass-based smart windows have been studied extensively, there is a disadvantage that the existing windows need to be completely replaced. In this study, an adhesive film-type smart windows was developed by combining a thermosensitive hydrogel on a transparent PET film then the acrylic adhesive layer was further added. Covalent bond formed between acrylic adhesive layer and hydrogel layer lead strong combination of the layers, which is essential for the installation/dis-installation. For the prepared film-type smart windows, the optical transition from a transparent state to an opaque state can be switched by the phase transition of the thermosensitive hydrogel. The developed smart window film is promising in that it can be easily attached to existing windows rather than replacing the part. |
