摘      要：Pressure-driven reverse osmosis membrane has important application in seawater *** by the structure of aquaporin,we established and studied the mechanism of the structure of multilayer graphene with tapered channels as reverse *** water flux of multilayer graphene with tapered channels was about 20%higher than that of parallel graphene *** flow resistance model was established,and the relationship between flow resistance and opening angles was *** relationship between flow resistance and outlet size was also *** means of molecular dynamics simulation,slip coefficients of multilayer graphene with tapered channel were obtained and verified by the contact angle of *** show that the permeability of graphene with tapered channel is about three orders of magnitude higher than that of commercial reverse osmosis membrane and the desalination rate is 100%.Temperature difference between the two sides of the tapered channel will promote the water flux positively.
