Abstract

•A fast NIPS forms the thin layer and finger-like pores•A slow NIPS forms the sponge pores•Gas from a foaming reaction gathers in the center to form the bore•Hollow fiber membranes are fabricated by dual pore formation mechanism

Novel hollow fiber membranes were developed by dual pore formation mechanism. The formation mechanism of hollow fiber membranes spun through single orifice spinneret was explained by combination of foaming reaction and conventional non-solvent induced phase separation. Structure of the hollow fiber membranes was examined by scanning electronic microscopy and BET analysis. The hollow fiber membranes have excellent mechanical property and can be used for dyes separation. The highly tunable hollow fiber membranes possess promising applications in separation.

Graphical abstractA fast non-solvent induced phase (NIPS) separation forms the thin layer and finger-like pores, and a slow NIPS forms the sponge pores. Gas from a foaming reaction gathers in the center to form the bore. Hollow fiber membranes are fabricated by dual pore formation mechanism combining these two processes.Figure optionsDownload full-size imageDownload as PowerPoint slide
