PROBLEM TO BE SOLVED: To provide a hollow fiber carbon membrane that is easily manufactured, enables miniaturization of a device, and has superior performance of water separation and permeability; and to provide a separation membrane module employing the same and a method of manufacturing the hollow fiber carbon membrane.SOLUTION: A hollow fiber carbon membrane includes a first hollow fiber carbon membrane, and a second carbon film arranged on an outer surface of the first carbon film, wherein the second carbon film is the hollow fiber carbon membrane containing a metallic element and a sulfur element. Also, a separation membrane module employing the same and the method of manufacturing the hollow fiber carbon membrane are provided.
摘要:
Provided is a carbon nanostructure-metal composite nanoporous film in which a carbon nanostructure-metal composite is coated on one surface or both surfaces of a membrane support having micro- or nano-sized pores. A method for manufacturing a carbon nanostructure-metal composite nanoporous film, includes: dispersing a carbon nanostructure-metal composite in a solvent at the presence of a surfactant and coating the carbon nanostructure-metal composite on one surface or both surfaces of a membrane support; and fusing the metal on the membrane support by heating the coated membrane support. The metal in carbon nanostructure-metal composite nanoporous film melts at a low temperature since a size of a metal of the carbon nanostructure-metal composite is several nm to several-hundred nm.
摘要:
Free-standing ordered mesoporous carbon films and form factors are prepared by depositing an aqueous precursor mixture that includes a water soluble carbon precursor, a non-ionic surfactant, and an oil onto a substrate or scaffold, drying the precursor mixture, and then cross-linking and heat treating (carbonizing) the carbon precursor. After carbonization, the ordered mesoporous carbon films and form factors include discrete domains of ordered, mesoscale pores.
