abstract = {Isoporous asymmetric
polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) hollow
fiber membraneswere successfully made by a dry-jet wet
spinning process. Well-defined nanometer-scale pores
around20e40 nm in diameter were tailored on the top surface
of the fiber above a non-ordered macroporouslayer by
combining block copolymer self-assembly and non-solvent
induced phase separation (SNIPS).Uniformity of the
surface-assembled pores and fiber cross-section morphology
was improved byadjusting the solution concentration, solvent
composition as well as some important spinning
parameterssuch as bore fluid flow rate, polymer solution
flow rate and air gap distance between the spinneretand the
precipitation bath. The formation of the well-organized
self-assembled pores is a result of theinterplay of fast
relaxation of the shear-induced oriented block copolymer
chains, the rapid evaporationof the solvent mixture on the
outer surface and solvent extraction into the bore liquid on
the lumen side,and gravity force during spinning. Structural
features of the block copolymer solutions were
investigatedby small-angle X-ray scattering (SAXS) and
rheological properties of the solutions were examined
aswell. The scattering patterns of the optimal solutions for
membrane formation indicate a disorderedphase which is very
close to the disorder-order transition. The nanostructured
surface and cross-sectionmorphology of the membranes were
characterized by scanning electron microscopy (SEM). The
waterflux of the membranes was measured and gas permeation
was examined to test the pressure stability ofthe hollow
fibers.},
