METHOD OF MANUFACTURING POROUS METAL CAPILLARY TUBE AND POROUS METAL CAPILLARY TUBE MANUFACTURED BY SAME

摘要

The present invention relates to a method of manufacturing a porous metal capillary tube with high gas permeability and excellent machinery stability. The method of manufacturing the porous metal capillary tube comprises: a raw material mixing step of mixing up nickel, a polymer, and a polymer solvent which are raw materials for non-solvent induced phase separation; a precursor composing step of composing a nickel precursor by performing a non-solvent induced phase separation process with respect to the mixed raw materials; and a nickel sintering step of sintering the nickel precursor by thermally processing the nickel precursor. The method of manufacturing the porous metal capillary tube is capable of obtaining an effect of manufacturing the porous metal capillary tube with high gas permeability due to a thin thickness and a three-dimensional porous structure and excellent machinery stability by manufacturing the porous metal capillary tube by thermally processing the nickel precursor manufactured through the non-solvent induced phase separation process. In addition, the method of manufacturing the porous metal capillary tube of the present invention is capable of manufacturing the porous metal capillary tube mechanically stable at a relatively low sintering temperature; thereby obtaining an effect of lowering costs required to manufacture the porous metal capillary tube appropriate for a supporter of a separation film.;COPYRIGHT KIPO 2017
