About the Lab
Professor Hyun Wook Jung's research lab specializes in the design and fabrication of advanced functional materials, with a primary focus on polymer-based membranes and hydrogels for water treatment and biomedical applications. The lab investigates innovative fabrication techniques—such as electrospinning, slot coating, and UV/thermal polymerization—to develop ultrathin, highly selective, and biofouling-resistant membranes for reverse osmosis and separation processes. A key research direction involves tailoring the crosslinking dynamics, mechanical properties, and swelling behavior of poly(ethylene glycol)-based hydrogels to enable stimuli-responsive performance and enhanced durability. The lab also explores biomimetic surface patterning and nanofiber engineering to improve material performance in real-world environmental and biological conditions.

The dual-layer slot coating technique can fabricate a sub-10 nm ultrathin, highly selective membrane outperforming commercial reverse osmosis membranes.
Abstract Electrospinning experiments for solutions of two polymers with different crystallization rates, polylatic acid (PLA), and nylon 6 solutions have been carried out. Hexafluoroisopropanol (HFIP) was used as a common solvent to dissolve both PLA and nylon 6. Using the fact that nylon 6 has the faster crystallization rate than PLA, the effect of thermal annealing conditions on the crystal structures of two electrospun fibers has mainly been studied via thermal and mechanical analysis. First,
ABSTRACT The gelation and crosslinking features of poly(ethylene glycol) (PEG) hydrogels were scrutinized through the UV polymerization processes of poly(ethylene glycol) methacrylate (PEGMA) and poly(ethylene glycol) dimethacrylate (PEGDMA) mixtures. The real‐time evolutions of the elastic moduli of the prepolymerized mixtures with different crosslinking ratios of PEGMA and PEGDMA and the photoinitiator concentrations were measured during photopolymerization. The rheological properties were com
This study investigates the crosslinking dynamics and swelling properties of pH-responsive poly(ethylene glycol) (PEG)/poly(acrylic acid) (PAA) interpenetrating polymer network (IPN) hydrogels. These hydrogels feature denser crosslinked networks compared to PEG single network (SN) hydrogels. Fabrication involved a two-step UV curing process: First, forming PEG-SN hydrogels using poly(ethylene glycol) diacrylate (PEGDA) through UV-induced free radical polymerization and crosslinking reactions, th
