主　　题：carbon nanotubes hydrogen bonding network facilitated water transport salt rejection desalination 

摘      要：The development of membranes featuring carbon nanotubes(CNTs)have provided possibilities of next-generation solar desalination *** solar desalination,the microstructures and interactions between the filter membrane and seawater play a crucial role in desalination *** the mechanisms of water evaporation and ion rejection in confined pores or channels is necessary to optimize the desalting ***,using non-equilibrium molecular dynamics simulations,we found that continuous water-water hydrogen bonding network across the rims of CNTs is the key factor in facilitating water transport through *** the continuous hydrogen bonding network,the water flux is two times of that without the continuous hydrogen bonding *** CNT arrays,each CNT transports water molecules and rejects salt ions *** on these observations,using CNT arrays consisted with densely packed thin CNTs is the most advisable strategy for evaporation desalination,possessing high transport flux as well as maintaining high salt rejection.
