Recent developments in the preparation and assembly of two-dimensional plate materials in Langmuir–Blodgett films: a review

In recent years, two-dimensional (2D) plate materials have become the most attractive class of candidate materials for a wide range of potential applications due to their unique structural characteristics and physicochemical properties. Starting from graphene, 2D plate materials have become a large family with many members and diverse categories. Especially in recent years, we have made some significant breakthroughs in the field of 2D materials. Langmuir–Blodgett (LB) technology is an advanced technology for preparing ultrathin films with highly ordered molecules by using its unique dynamic interface in the preparation process, which can effectively control and adjust the film material with layered nanostructures. With the advancement of LB technology, different thin film materials need to be prepared to realize various functions. This paper summarizes the research progress and future perspectives of LB technology based on 2D materials.
