Abstract：

On the basis of the poly (4-methyl-1-pentene) (PMP)/myristic acid (MA) system, PolarClean,a non-solvent for PMP with water-soluble and non-toxic, was added to enable the PMP/MA/PolarClean system to undergo hybrid induced phase separation (HIPS), and successfully obtaining PMP hollow fiber membranes with dense surface and bicontinuous gradient pore structure inside. A systematic investigation was conducted on the effect of the MA/PolarClean mass ratio and PMP mass fraction on the morphology, strength, bubble point, nitrogen permeability, and other properties of hollow fiber membranes. The results showed that when the mass ratio of MA/PolarClean was 5∶1 and the PMP mass fraction was 40%, the comprehensive performance of PMP hollow fiber membranes was similar to that of commercial membranes, demonstrating good application potential.
