Recent Advances in Two-Dimensional Polymer Materials

Two-dimensional (2D) materials have attracted much interest in recent years. This review focuses on both layered materials and nanosheets with 2D anisotropic structures. The chemical interactions in the lateral and vertical directions play important roles for the flexibility of the layered structures enabling the dynamic functions as polymer materials. A variety of dynamic properties can be extracted from the flexibility control. Section 1 summaries the background and structural characteristics of these 2D materials. Section 2 shows the layered materials exhibiting the dynamic functions including our recent works. Section 3 introduces exfoliated nanosheets from layered materials and their applications. Section 4 focuses on the designed new 2D materials in recent works. Whereas classical 2D materials were rigid and static in previous works, the more flexible and dynamic structures are achieved in recent works. Such 2D materials can be regarded as a new family of polymer materials.
