Abstract

Abstract: The tape exfoliation method is still the easiest and most convenient way to obtain large-area two-dimensional (2D) monolayers in experimental research. Recently, there are some important advances in tape exfoliation method for large 2D monolayer materials. This review mainly introduced three kinds of new tape exfoliation methods including modified Scotch tape exfoliation method, metal-assisted tape exfoliation method and gel-assisted tape exfoliation method. We highlight the operation process and exfoliated mechanism of each method. We point out several problems to be solved and give an outlook on the development direction of the new tape exfoliation method. We hope this review will help researchers, especially for beginners, quickly and easily obtain a variety of 2D monolayers for their own experiments.
