which is much closer to an "ideal" smooth impenetrable solid substrate. No dependence of the scaling relationship on the strength of the fluid-substrate interactions was observed, however, with the results at the graphene and "strong" (same particle arrangement but double the interaction strength) substrates showing the same behaviour. This result indicates that patterning of the substrate may be an effective method to favour a more side-on alignment, as has been previously observed, although further study would be required to fully understand this behaviour.
