Improper control of air gap interval during hollow fiber membranes (HFMs) spinning may lead to structural defects such as inner lumen deformations and macrovoids. In the current work, PVDF HFMs were prepared by manipulating air gap intervals at 5, 10, 15, 20, and 25 cm, using dry-wet spinning mechan...
