DFT simulation for the interactions between dextran and TMD. Potential energy of interaction between two parallel monolayers of WS2 a with and b without dextran. The central image illustrates an exfoliation process in two cases. Binding energy of the hydrophilic hydroxyl groups of dextran with c pure WS2, d oxygen-defective WS2, and e hydroxyl-defective WS2
