Electrochromic and self-cleaning intelligent window and preparation method thereof
The invention relates to an electrochromic and self-cleaning intelligent window and a preparation method thereof.The intelligent window comprises a first hydrophobic transparent film, an elastic backing ring and a second hydrophobic transparent film which are stacked in sequence; the first hydrophobic transparent film is coated with an elastic latticed conducting layer, a sealed filling cavity is formed among the first hydrophobic transparent film, the elastic backing ring and the second hydrophobic transparent film, and the filling cavity is filled with thermosensitive hydrogel; the preparation process of the thermosensitive hydrogel comprises the following steps: adding N-isopropylacrylamide and hydroxypropyl methyl cellulose into a deionized water solvent, and uniformly mixing to obtain a first solution; after the first solution is in a transparent state, methylene bisacrylamide, ammonium persulfate and sodium hydrogen sulfite are dissolved in the first solution in a stirring state, and thermosensitive hydrogel is obtained; wherein the mass ratio of the N-isopropylacrylamide to the hydroxypropyl methyl cellulose to the methylene bisacrylamide to the ammonium persulfate to the sodium hydrogen sulfite is 16000: 1500: 54.4: 50: 30. The problem that an existing self-cleaning intelligent window is poor in light transmittance and flexibility is solved.
本申请涉及一种电致变色且自清洁的智能窗及其制备方法，其中，该智能窗包括：依次层叠的第一疏水透明膜、弹性垫环和第二疏水透明膜；第一疏水透明膜上涂覆有弹性且呈网格状的导电层，第一疏水透明膜、弹性垫环和第二疏水透明膜之间形成密封的填充腔，填充腔内填充有热敏水凝胶；热敏水凝胶的制备工艺包括：将N‑异丙基丙烯酰胺和羟丙基甲基纤维素加入去离子水溶剂中并均匀混合，得到第一溶液；待第一溶液呈透明状态后，在搅拌状态下将亚甲基双丙烯酰胺、过硫酸铵和亚硫酸氢钠溶解在第一溶液中，得到热敏水凝胶；其中，N‑异丙基丙烯酰胺、羟丙基甲基纤维素、亚甲基双丙烯酰胺、过硫酸铵和亚硫酸氢钠的质量为16000:1500:54.4:50:30。本发明解决了目前自清洁智能窗的透光度和柔性较差的问题。
