  In this work we have investigated, by fully atomistic reactive (force field
ReaxFF) molecular dynamics simulations, some aspects of impact dynamics of
water nanodroplets on graphdiyne-like membranes. We simulated
graphdiyne-supported membranes impacted by nanodroplets at different velocities
(from 100 up to 1500 m/s). The results show that due to the graphdiyne porous
and elastic structure, the droplets present an impact dynamics very complex in
relation to the ones observed for graphene membranes. Under impact the droplets
spread over the surface with a maximum contact radius proportional to the
impact velocity. Depending on the energy impact value, a number of water
molecules were able to percolate (pass through) the nanopore sheets. However,
even in these cases the droplet shape (liquid state) is preserved and the main
differences between the different impact velocities cases reside on the
splashing pattern at the maximum spreading.
