Graphene multilayer composite heat insulation film, preparation method and application thereof
The invention discloses a graphene multilayer composite heat insulation film, a preparation method and application thereof, and belongs to the technical field of heat insulation films or heating films. The graphene multilayer composite heat insulation film comprises a graphene layer, a flexible polymer film layer, a silica sol layer and a glass fiber reinforced silicon dioxide aerogel layer whichare sequentially arranged from top to bottom. Graphene is prepared into graphene slurry to be organically combined with an existing glass fiber reinforced silica aerogel thermal insulation material, excellent thermal, mechanical and other properties of graphene are used for enhancing isolation of external heat and the strength of the heat insulation film, and the advantages of the two materials are brought into play to the maximum extent. Moreover, after the left end and the right end of the graphene layer in the graphene multilayer composite heat insulation film are connected to copper sheetelectrodes, the graphene multilayer composite heat insulation film can also be used as a graphene electrothermal film, and the obtained electrothermal film is uniform in heating, low in use voltage and good in electrothermal performance, and can be widely applied to the living fields of heating floors, building heating, far-infrared health care and medical treatment and the like.
本发明公开了一种石墨烯多层复合隔热膜及其制备方法和应用，属于隔热膜或发热膜技术领域。本发明的石墨烯多层复合隔热膜，包括从上至下依次设置的石墨烯层、柔性高分子膜层、硅溶胶层和玻璃纤维增强二氧化硅气凝胶层。本发明将石墨烯制成石墨烯浆料与现有玻璃纤维增强二氧化硅气凝胶隔热材料有机结合，将石墨烯优异的热学及力学等方面性能用以加强隔绝外部热量以及隔热膜强度，最大限度的发挥了两种材料的优势。并且，在本发明石墨烯多层复合隔热膜中的石墨烯层左右两端接通铜片电极后亦可作为石墨烯电热膜，得到的电热膜发热均匀，使用电压低，具有良好的电热性能，可被广泛应用于发热地板、建筑取暖、远红外保健医疗等生活领域。
