Abstract: A model is proposed in which the interaction of a macromolecule (MM) with a single-layer graphene (SLG) is carried out by dangling interfacial molecular bonds. To estimate the energy of MM-SLG stitching, or adsorption energy (the index i numbers the broken bonds), a simple theoretical scheme, permitting to obtain analytical results, was used. The adhesion energy is defined as the sum of the terms $E^{ads}_iN_i$, where $N_i$ is the concentration of $i$-type dangling bonds. The obtained results are compared with experimental data on adhesion for various heterostructures

Keywords: macromolecule, graphene, charge transfer, adsorption, adhesion.
