Crosslinking of the model significantly enhances the friction force for BMI and epoxy, but not for the Benzoxazine over most of the range of velocities. The effect of polymerization for these three systems displays an inverse trend as seen from the interaction energy study, where polymerization reduced the interaction, yet increases the frictional force. Polymerization imposes additional restrictions on the movement of the monomeric units by the formation of a polymer network. The formation of a more rigid network causes a greater amount of coarsening (i.e. protrusion of constrained molecular groups into the flCNT surface) and thus increased interface friction, whereas un-crosslinked monomers can more easily conform to the flCNT surface and thus form a smoother interface with less friction. Figures and display the minimum and maximum polymer mass fraction models for the three systems for the unpolymerized and polymerized conditions, respectively. In Error! Reference source not found., the effect of polymer mass fraction on the frictional resistance is demonstrated for the entire collection of flCNT-polymer models and no discernable trend was observed for the range of mass fractions. The results from 10 m/s sliding velocity were chosen for comparison. For all the models, the friction force increases post-polymerization. As seen in Figure , the observations indicate an inverse relation between the friction force and interaction energy. That is, polymers exhibiting higher interaction energies exhibited lower frictional resistance, and the systems with lower interaction energy generally displayed better friction force. Also, polymerization degrades the interaction energy of all the polymers, however, it enhances the friction force for the same systems. Figure from the supporting information shows the data for other velocities and similar trends were observed.
