Abstract: A separation membrane for removing contaminants comprises: a hydrophobic membrane; and a graphene oxide layer formed to cover the hydrophobic membrane partially or wholly, wherein one surface of the hydrophobic membrane facing the graphene oxide layer has been hydrophilic-processed. The separation membrane is capable of enhancing removal efficiency on volatile contaminants, while maintaining a performance of the conventional separation membrane. The separation membrane is useful as a separation membrane for water treatment. Further, the separation membrane may be comprised in a membrane distillation apparatus, or may be utilized as a filter of a humidifier or a water purifier.

Abstract: The present invention relates to a hollow-fibre membrane having a novel structure and to a production method therefor. The hollow-fibre separation membrane of the present invention has an outermost shell surface pore size of between 0.001 and 0.05 μm and a mean pore size of between 0.01 and 0.1 μm while having, in sequence from the outermost shell surface, a dense sponge structure, a finger-like sponge structure and a mixed sponge-bead structure; and, because of this specific triple structure, the invention has outstanding mechanical strength, porosity and water permeability alike while also having a high performance whereby it is possible to eliminate even viruses.
