摘　　要：Different from the conventional polymeric separation membranes having a wide flexible-pore size distribution,layered graphene-based films with interconnected nanochannels provide narrowly well-defined nanopore-size distribution and thus are extremely advantageousDifferent from the conventional polymeric separation membranes having a wide flexible-pore size distribution, layered graphene-based films with interconnected na- nochannels provide narrowly well-defined nanopore-size distribution and thus are extremely advantageous for precise liquid filtration and separation. Recently, con- siderable progress has been achieved in graphene-based membranes for molecular sieving in water. For example, it was found that sub-micrometer-thick graphene oxide （GO） membranes were almost impermeable to liquids, vapors, or gases but allowed unimpeded permeation of water [1] because of the nearly frictionless flow of water molecules through the two-dimensional hydrophobic nonoxidized capillaries.
