Construction method for preparing oriented boron nitride aerogel at low cost without freeze-drying method
The invention discloses a low-cost construction method for preparing oriented boron nitride aerogel without a freeze-drying method, and provides a low-cost construction method for preparing oriented boron nitride aerogel without a freeze-drying method in order to realize preparation of boron nitride aerogel with an oriented structure. In order to realize mutual connection between boron nitride sheet layers, graphene oxide is introduced into a system and is used as chemical glue to realize sheet layer bonding. In order to improve energy consumption and time consumption of traditional freeze drying, chemical hydrothermal reduction and ice template orientation are combined, and air drying is directly adopted to realize preparation of the boron nitride aerogel.
本发明公开了一种低成本无需冷冻干燥法制备取向氮化硼气凝胶的构筑方法，所述方法为实现具有取向结构氮化硼气凝胶的制备，提供了一种低成本无需冷冻干燥法制备取向氮化硼气凝胶的构筑方法。本发明为了实现氮化硼片层间的相互连接，在体系内引入氧化石墨烯，作为化学胶水实现片层粘结。为改良传统冷冻干燥的耗能耗时，结合化学水热还原与冰模板取向，直接采用空气干燥实现氮化硼气凝胶的制备。
