2D Nanomaterials with Hierarchical Architecture for Flexible Sensor Application

The research into two-dimensional (2D) nanomaterials is in its heyday and will continue to develop into a cutting-edge subject in the materials science field. Although 2D nanomaterials (i.e., black phosphorus, graphene, titanium carbide, transition metal dichalcogenides, and transition metal oxides) have been increasing interest in flexible electronic applications due to their diversity and fascinating properties, their restacking or aggregation in the preparation of sensing materials has severely limited their further exploration into the context of flexible electronic applications. Extensive efforts have focused on designing these 2D nanomaterials to match the needs of a specific applications. The latest research shows that rational structural design can effectively break through the current material limitations and show great promise in improving sensor performance to unprecedented levels in the field of flexible electronics. In this chapter, the recent advances of 2D nanomaterials with hierarchical architectures are discussed, focusing on their structural engineering strategies, structure advantages, and applications.
