Post-polymerization, the interaction energy plots shift upwards indicating loss of interaction strength due to the new networked polymer topology. For benzoxazine, the effect of polymerization on the interaction energy is significant, however, saturation of the interface for the polymerized system has no effect on the interaction energy. In the case of epoxy and BMI, the interaction energy shifts slightly but maintains the same trend as observed with the unpolymerized models. With BMI, preferential adsorption of BMPM is still present but less impactful. Figure shows the orientation of the phenyl rings in the monomer and polymer structures with respect to the flCNT surface. It is well-documented that phenyl groups promote aromatic-aromatic non-bonded stacking, a.k.a. π-π stacking . The orientations were computed by extracting the dihedral angles of the phenyl rings within the polymer layers. The angle was calculated with respect to the X-Y plane of the flCNT surface, ignoring deviations caused due to slight waviness as seen in Figure . Lower angles represent greater degrees of alignment with the flCNT surface. The monomer/polymer mass fractions used for this analysis correspond to the converged interaction energies, specifically, BMI: 58.52%, Epoxy: 58.66%, and Benzoxazine: 56%. This analysis was conducted to provide physical insight into the interaction energy trends. Earlier studies have shown the non-bonded interactions between the aromatic groups is a strong contributor towards the interaction energy . Figure clearly shows the decrease in interfacial interaction when the monomers undergo polymerization and result in lower numbers of phenyl rings aligned with the interface. The creation of networks results in additional mobility constraints which results in higher angles between the phenyl rings and the flat aromatic surface. Within each polymer system, the number of phenyl rings with less than 10 o angle is reduced after crosslinking. All three resins systems demonstrate similar patterns in interaction energy and polymerization, however, the preferential adsorption in BMI helps in limiting the reduction in interaction energy after polymerization, which is highlighted in Figure . The epoxy models show a higher drop in the interaction energy since neither of the two components strongly prefer the flCNT surface.
