Research Interest

​Fabrication of hollow fiber membranes using newly synthesized and commercially available polymer for various membrane application (gas, water or solvent separation). Bringing innovation within HF fabrication process (NIPS, TIPS, multi-bore fibers, corrugated fibers, etc.) and post modification (coating, plasma etching, pyrolysis etc.).
