The interaction energy (IE) between individual chemical groups in the droplets and the surface was calculated using the 'compute group/group' command in LAMMPS. The LAMMPS package determines the IE using where 𝑰𝑬 𝟏,𝟐 is the interaction energy between atoms in group 1 and group 2; 𝑬 𝟏 is the energy of atoms present in group 1; 𝑬 𝟐 is the energy of atoms present in group 2; and 𝑬(𝟏, 𝟐) is the total energy of atoms in present in groups 1 and 2.
