In an attempt to shed some light into the issue, we did a thorough HBs analysis to unravel their role in determining the transport properties of water in the 2D channels between the GO layers. Our analysis revealed that while the inter-molecular HBs at the GO/water interface are very dynamic (i.e., the life time of the individual HB is quite short), they can form bridges between the two parallel GO layers. These HB bridges seem to play a crucial role in slowing down the diffusion of the confined water. In the next section, we discuss these HB bridges and their role in detail.
