“…5,6 Combined with advanced fabrication methods, e.g. , electrostatic spinning, 7,8 chemical vapor deposition, 9,10 interface aggregation 11–13 and layer-by-layer assembly, 14,15 a range of biopolymers, 16,17 ceramic 18,19 and inorganic nanomaterials 20,21 have been used to improve the water separation capability of these films. Furthermore, due to the size difference between dyes and salt ions, the regulation of film pores and the construction of fluid channels has become the focus of screening dyes and salts.…”
