PURPOSE: A porous poly acrylonitrile fiber and a manufacturing method thereof are provided to manufacture a porous fiber which includes a hollow structure by using a microfluidic channel system. CONSTITUTION: A manufacturing method of porous poly acrylonitrile fiber comprises the following steps: manufacturing a porous fiber which includes a hollow structure by using a microfluidic channel system; and injecting fluid including poly acrylonitrile and dimethyl sulphoxide into the microfluidic channel system in a core flow form and injecting dimethyl sulfoxide solution in a sheath flow form. The content of the poly acrylonitrile in the core flow form is 0.1-10 parts by weight based on 100 parts by weight of the total core flow fluid. |
