A Review on High‐Efficiency Transfer of Graphene Films Free from Defects and Contamination

Graphene, owing to its exceptional electronic, optical, thermal, and mechanical properties, has emerged as a highly promising material. Currently, the synthesis of large‐area graphene films on metal substrates via chemical vapor deposition remains the predominant approach for producing high‐quality graphene. To realize the potential applications of graphene, it is essential to transfer graphene films to target substrates in a manner that is non‐destructive, clean, and efficient, as this significantly affects the performance of graphene devices. This review examines the current methods for graphene transfer from three perspectives: non‐destructive transfer, clean transfer, and high‐efficiency transfer. It analyzes and compares the advancements and limitations of various transfer techniques. Finally, the review identifies the key challenges faced by current graphene transfer methods and anticipates future developmental prospects.
