#$%^&*AU2020101082A420200723.pdf#####ABSTRACT The present invention provides a method for preparing a two-dimensional/one-dimensional (2D/1D ) heterogeneous nanochannel membrane. The method includes the following steps: step 1: dissolving graphene oxide (GO) in a piperazine aqueous solution, and conducting ultrasonic treatment at room temperature to obtain a uniformly dispersed first solution; step 2: adding the first solution dropwise to an upper layer of a porous anodic aluminum oxide (AAO) film, and obtaining a first composite film with a GO film layer and a porous AAO film layer after the solvent is evaporated at room temperature; and step 3: adding a trimesoyl chloride solution dropwise to an upper surface of the GO film layer of the first composite film, and drying to obtain the 2D/lD heterogeneous nanochannel membrane. The present invention also provides a 2D/D heterogeneous nanochannel membrane prepared by the method and use thereof in ocean salinity energy conversion. 12FIG. 4 2.0. ~1.8 GO ~1.2 F F -3 U1 1 1.40, l 1- W4 12 3 1.e C B~nkAO .10, is 10......................
