2D materials, also termed 2D nanosheets, have attracted significant interest due to their unique molecularly thin 2D structure to exhibit various attractive properties. They include a diverse range of materials, such as graphene, chalcogenide, oxide, hydroxide, and carbide. Such 2D materials can be produced via the delamination of their precursor layered compounds. Different from graphite and van der Waals layered compounds, there are a wide range of layered materials accommodating interlayer counterions, serving as a trigger for delamination upon exchange with suitable species. Since interlayer galleries swell evenly and infinitely, single-layer nanosheets can be obtained in high yield in the form of a colloidal suspension.

二维材料的高度有序单层排列及其应用

2D 材料，也称为 2D 纳米片，由于其独特的分子薄 2D 结构而表现出各种有吸引力的特性，引起了人们的极大兴趣。它们包括各种材料，例如石墨烯、硫族化物、氧化物、氢氧化物和碳化物。这种二维材料可以通过其前体层状化合物的分层来生产。与石墨和范德华层状化合物不同，有多种层状材料可容纳层间抗衡离子，在与合适的物质交换时充当分层的触发因素。由于层间通道均匀且无限膨胀，因此可以以胶体悬浮液的形式高产率获得单层纳米片。
