Water-holey graphene interactions

ORAL

Abstract

We employ Molecular Dynamics (MD) simulations to probe the interaction of a water nanodrop with a holey graphene (HG) matrix. HG is a particular form of structurally defective nanoporous graphene, where multilayers of nanoporous graphene get arranged in form of vertically separated stacks with inter-stack separation of several nanometers.
The HG system has been known to produce enhanced ion-accessible graphene surface area. Here we probe the interaction of water nanodrop with HG in the presence and in absence of an applied force. We recover highly interesting wetting states including states that resemble wetting on a fiber. In the presence of an external force, on the other hand, we show that the time of application of the force can be regulated to generate wetting states that suggest a massively increase water-accessible surface area.
