一种二氧化钛/石墨烯柔性电热膜的制备方法
摘要：
本发明公开了一种二氧化钛/石墨烯柔性电热膜的制备方法，将PET膜分别用去离子水和用乙醇清洗，并晾干；称取石墨烯加入TiF4溶液中反应，反应结束后，将沉淀用水和乙醇清洗，然后干燥得到TiO2/石墨烯粉末；分别称取丙烯酸树脂、丙二醇甲醚乙酸酯、丙二醇甲醚和二丙二醇甲醚置于反应釜中，通过均相反应后得到丙烯酸树脂溶液；称取TiO2/石墨烯粉末和炭黑加入丙烯酸树脂溶液中，搅拌得到TiO2/石墨烯浆料；将TiO2/石墨烯浆料涂覆于PET膜上，干燥即得到TiO2/石墨烯柔性电热膜。本发明制备TiO2/石墨烯柔性电热膜工艺简单、重复性好、成本低。
摘要（英）：

The invention discloses a preparation method of a titanium dioxide/graphene flexible electrothermal film, which comprises the following steps: respectively cleaning a PET film with deionized water andethanol and air-drying the PET film; weighing graphene, adding the graphene into a TiF4 solution for a reaction, cleaning the precipitate with water and ethanol after the reaction is finished, and then drying the precipitate to obtain TiO2/graphene powder; respectively weighing acrylic resin, propylene glycol methyl ether acetate, propylene glycol methyl ether and dipropylene glycol methyl ether,adding the reactants into a reaction kettle, and carrying out a homogeneous reaction to obtain an acrylic resin solution; weighing TiO2/graphene powder and carbon black, adding the TiO2/graphene powder and the carbon black into the acrylic resin solution, and stirring the solution to obtain TiO2/graphene slurry; and coating a PET film with the TiO2/graphene slurry, and drying the PET film to obtain the TiO2/graphene flexible electrothermal film. The method for preparing the TiO2/graphene flexible electrothermal film is simple in process, good in repeatability and low in cost.
