Stimuli‐Responsive 2D Materials Beyond Graphene

Abstract The development of graphene‐based responsive material has gained tremendous attention in recent decades and has led to search for alternative 2D materials beyond graphene. In recent years, due to their large surface‐to‐volume ratio, atomic thickness, and excellent selectivity of molecular adsorption, 2D materials beyond graphene, including hexagonal boron nitride, transition metal dichalcogenides, black phosphorus, and MXenes, have exhibited great potential in stimuli‐responsiveness. This review explores the five representative stimulus behaviors (temperature, light, gas, electric, and water) of 2D materials beyond graphene and their applications in sensors, detectors, smart devices, photothermal therapy, and actuators. To understand these stimuli‐responsive behaviors in depth, the typical responsive mechanisms are also described. This review summarizes the recent progress in stimuli‐responsive 2D materials beyond graphene and future perspectives to inspire broader and more combined designs using multiple stimuli, and to motivate more exciting developments based on these promising 2D materials beyond graphene.
