Naturally occurring proteins are used as dispersants for aqueous ultrasonic exfoliation of 2D materials. However, their structures are far from optimal for these applications. A series of synthetic bifunctional chimeric polyproteins were engineered to improve the exfoliation yield and quality of the 2D materials. They contain an amphiphilic protein, hydrophobin, to serve as the anchoring point that binds specifically and strongly to graphene layers as well as tandem repeats of a globular protein GB1 to respond and transfer the ultrasonic force for efficient mechanical exfoliation.
