Summary: Transition metal dichalcogenides (TMDs) are promising two-dimensional materials for intelligent and flexible electronic devices due to their superior mechanical and electrical conductivity. However, their further applications are limited by their tendency to aggregate. Surface chemical modification is commonly used to improve the dispersity of TMD nanomaterials, but there are still constraints in terms of functionalization methods and practical application. Therefore, developing innovative surface modification systems is challenging.
