研究室紹介
Professor Hyun-Won Kweon's research lab specializes in the development of sustainable, high-performance materials from natural biopolymers, with a focus on silk sericin and lignin. The lab explores the self-assembly mechanisms of fibroin and sericin during natural silk spinning, aiming to understand and harness their synergistic interactions for advanced biomaterials. A key research direction involves designing reusable, eco-friendly adsorbents from agricultural by-products for environmental remediation, particularly for heavy metal removal such as Cr(VI). The lab integrates materials science, biopolymer chemistry, and green engineering to create functional materials with applications in environmental sustainability and biomedicine.

15In the present study, novel adsorbents having high adsorption capability and reusability were prepared using agricultural by-products: silk sericin and lignin. Silk sericin and lignin blend beads were successfully prepared using simple coagulation methods for the removal of hexavalent chromium (Cr(VI)) from aqueous solution. A 1 M lithium chloride (LiCl)/dimethyl sulfoxide (DMSO) solvent system successfully dissolved both sericin and lignin and had sufficient viscosity for bead preparation. Comp
Natural silk spinning offers several advantages over the synthetic fiber spinning, although the underlying mechanisms of this process are yet to be fully elucidated. Silkworm silks, specifically B. mori, comprise two main proteins: fibroin, which forms the fiber, and sericin, a coextruded coating that acts as a matrix in the resulting nonwoven composite cocoon. To date, most studies have focused on fibroin's self-assembly and gelation, with the influence of sericin during spinning receiving litt
