日前,哈尔滨工业大学土木工程学院李惠教授课题组徐翔等在Advanced Materials杂志上发表了《自然干燥方法制备具有超弹性和可调节泊松比特性的石墨烯气凝胶》的论文。为了在宏观尺度上利用石墨烯的优异特性,构筑石墨烯的宏观体结构成为目前材料领域的研究热点。在众多石墨烯组装体结构中,石墨烯气凝胶(Graphene Aerogel)是最引人注目的结构之一。目前,三维石墨烯气凝胶宏观体的制备过程需要采用高成本、低产出、难操作的冷冻干燥技术或超临界干燥
Recently, Xu Xiang et al., A research group led by Professor Li Hui from Harbin Institute of Technology, published a paper on “Natural Drying Method for Preparing Graphene Airgel with Super-elasticity and Poisson’s Ratio Adjustable” in Advanced Materials. In order to utilize the excellent properties of graphene on a macroscopic scale, the macrostructure of graphene has become the hotspot in the field of materials. Among many graphene assembly structures, Graphene Aerogel is one of the most striking structures. Currently, the preparation of 3D graphene airgel macrostructures requires the use of high-cost, low-output, difficult-to-operate freeze-drying techniques or supercritical drying
