  Disclosed is a hollow fiber that includes a hollow positioned at the center of the hollow fiber, macropores positioned at adjacent to the hollow, and mesopores and picopores positioned at adjacent to macropores, and the picopores are three dimensionally connected to each other to form a three dimensional network structure. The hollow fiber includes a polymer derived from polyimide, and the polyimide includes a repeating unit obtained from aromatic diamine including at least one ortho-positioned functional group with respect to an amine group and dianhydride.

  本发明公开了一种中空纤维，该纤维包括位于中空纤维中心的中空、位于中空相邻位置的大孔、以及位于大孔相邻位置的中孔和微孔，微孔彼此三维连接以形成三维网络结构。中空纤维包括由聚酰亚胺衍生的聚合物，聚酰亚胺包括由芳香族二胺衍生的重复单元，芳香族二胺包括至少一个与胺基和二酸酐正交定位的官能团。

  Disclosed herein are a polyimide dope solution composition, a method for preparing a hollow fiber using the composition and a hollow fiber prepared by the method. More specifically, disclosed are a method for preparing a hollow fiber, comprising preparing a polyimide dope solution composition comprising polyhydroxyimide, polythiolimide or polyaminoimide, spinning the composition to prepare a hollow fiber, and thermally rearranging the hollow fiber, and the hollow fiber prepared by the method. In accordance with the method, a hollow fiber made of a high free volume polymer membrane can be prepared by spinning the dope solution composition to prepare a hollow fiber and thermally rearranging the hollow fiber via thermal treatment. The hollow fiber thus prepared exhibits excellent gas permeability and selectivity, thus being suitable for use as a gas separation membrane.
