Abstract: IN THIS STUDY, A NOVEL AND RECENTLY DEVELOPED FABRICATION METHOD FOR POLYMERIC HOLLOW FIBER MEMBRANE WAS INVESTIGATED TO FABRICATE MEMBRANES WITH VARIOUS STRUCTURES AND SURFACE PROPERTIES IN THE ULTRAFILTRATION (UF) AND NANOFILTRATION (NF) RANGE, FOR WHICH THE CONVENTIONAL OR CURRENT STATE OF TECHNOLOGY OFTEN NEED MULTIPLE OR DIFFERENT PROCESSES TO PREPARE THEM. THE METHOD IS BASED ON A VERSATILE ONE-STEP SPINNING METHOD THAT COMBINES THE EFFECT OF SIMULTANEOUS PHASE INVERSION AND CROSSLINKING OR ADSORPTION TOGETHER IN THE SPINNING PROCESS (OCCURRED IN THE SPINNERET). COMPARED TO THE TRADITIONAL PREPARATION APPROACH, THE NEW METHOD CAN REDUCE THE AMOUNT OF THE CROSSLINKING CHEMICAL OR FUNCTIONAL POLYMER REQUIRED AND THE TOTAL PROCESS STEPS FOR THE MODIFICATION OF HOLLOW FIBER MEMBRANES IN THEIR SELECTIVE SEPARATION LAYER STRUCTURE AND PROPERTY. THIS VERSATILE ONE-STEP SPINNING METHOD NOT ONLY CAN TAILOR THE MEMBRANE SURFACE CHARGE BUT ALSO ADJUST THE SURFACE WETTING PROPERTIES. THE MEM
