Abstract:
There are provided a reverse osmosis membrane comprising a porous support; a silver nanowire layer formed on the porous support; and a polyamide film formed on the silver nanowire layer, and a fabrication method of a reverse osmosis membrane, the method comprising coating a porous support with an aqueous amine solution including silver nanowires to form a silver nanowire layer; and bringing the silver nanowire layer into contact with an aliphatic hydrocarbide-based organic solution including acyl halide to form a polyamide film.
