Graphene-water interaction has been under scrutiny ever since graphene
discovery and realization of its exceptional properties. Several computational
and experimental reports exist that have tried to look into the interactions
involved, however, none of them addresses the issue in its entirety. We have
tested the inherent hydrophobic behavior of a small graphene in water droplet
by the means of MD simulations. The analysis has been extended to multiple
graphene flakes in water and their respective size dependent responses to water
droplet. Graphene retreats from water droplet to encapsulate it from the
surface. This response was highly dependent upon graphene size with respect to
water content. Additionally, we also report self-assembly of multilayered
graphene in water by means of MD simulations, an observation which can be
utilized to synthesize such structures in a cost-effective way by
experimentalists. To fully comprehend graphene behavior in water, graphene
deformation was analyzed in the presence of water molecules. It was noticed
that graphene wrinkled to wrap around water molecules and resisted complete
failure, one that is seen in case of a sole graphene sheet. Our work will not
only address the question about whether graphene is hydrophobic or hydrophilic
but also provide insight into the behavior of graphene surface and mobility
when exposed to water which can be exploited in numerous applications
