研究室紹介
Professor Dukjun Kim's research lab specializes in the design and synthesis of advanced functional materials, with a strong focus on nanomaterials for energy and biomedical applications. Key research directions include the development of shape-controlled hematite nanocrystals for photocatalytic and electrochemical applications, the engineering of superporous hydrogels for gastric retention and drug delivery, and the creation of high-performance polymer electrolytes for solid-state lithium batteries. The lab also explores proton transport in crosslinked polymers and hierarchical polymer architectures to enhance ionic conductivity and mechanical stability.

15We have developed a new green chemical approach for the shape-controlled synthesis of single-crystalline hematite nanocrystals in aqueous medium. FESEM, HRTEM and SAED techniques were used to determine the morphology and crystallographic orientations of each nanocrystal and its exposed facets. PXRD and HRTEM techniques revealed that the nanocrystals are single crystalline in nature; twins and stacking faults were not detected in these nanocrystals. The structural, vibrational, and electronic spe
Chitosan and glycol chitosan hydrogels were prepared, and their swelling behaviors in acidic solution were studied to investigate their application for gastric retention device. The optimum preparation condition of superporous hydrogels was obtained from the gelation and blowing kinetics measured at varying acidic conditions. Both the swelling rate and swelling ratio of glycol chitosan hydrogels were higher than those of chitosan hydrogels. Swelling behaviors were significantly affected by not o
Proton exchange membranes based on PAEK grafted with long aliphatic pendant groups which show good stability for VRFB applications.

The cast solvent effect on the structure and properties of sulfonated poly(ether ether ketone) (sPEEK) was studied. PEEK was sulfonated to have different sulfonation degrees of 65, 70, and 75%, and its membrane was prepared using the two types of solvents, N,N-dimethylacetamide (DMA) and 1-methyl-2-pyrrolidinone (NMP). Ionic cluster size was analyzed using small-angle X-ray scattering (SAXS), and it was correlated with a few essential membrane properties such as water uptake, methanol permeabili
