近年来,石墨烯基气凝胶(GAs)因其低密度、高比表面积及多孔结构等优异特性被广泛研究并在诸多应用领域内表现出极大的潜力。但是传统块状石墨烯基气凝胶往往具有设备依赖性强、材料尺寸大及量化生产性差等缺点,并且忽略了特定应用场景对材料形状尺寸的要求,从而限制了其实际应用与发展。石墨烯基气凝胶微球(GAMs)作为一种具有新颖结构的新型材料,不仅具有GAs的各种优势特征,而且具有灵活可控的尺寸及可量化生产能力等优点,大大丰富了GAMs的应用场景。本文将对GAMs的制备方法及其结构特征,以及在水污染处理、电磁波吸收、电催化等领域研究现状进行详细阐述,指出微球成形组装过程中的内在机制。 |

In recent years,graphene-based aerogels(GAs)have been extensively studied owing to the excellent characteristics of low density,high specific surface area and porous structure,which show great potential in many applications.The disadvantages of traditional bulk graphene-based aerogels, for instance,strong device-dependence,large size and poor scalable production,limit their practical application and development.Meanwhile,conventional preparation techniques ignore the requirements of materials shape and size for specific application scenarios.As a new aerogels display form with novel structure,graphene-based aerogel microspheres(GAMs)not only have various advantages of GAs but possess properties of flexible and controllable size and scalable production,which tremendously enrich the application scenarios of GAMs.The fabrication methods and structure of GAMs,as well as the application fields of water pollution treatment,electromagnetic wave absorption and electrocatalysis were elaborated in this review.Meanwhile,the internal mechanism of GAS during molding assembly process was also pointed out. |
