Professor Sung Hoon Jeong's research lab specializes in the development of advanced functional materials for sustainable energy and wearable technology applications. The lab focuses on nanomaterials engineering, particularly silver and titanium dioxide nanostructures, for antibacterial textiles and dye-sensitized solar cells (DSSCs). Key research directions include the fabrication of flexible, lightweight, and durable textile-based electronic components such as counter electrodes and photoanodes using carbon nanotubes and polymer matrices. The lab also emphasizes cost-effective, scalable synthesis methods to enhance energy conversion efficiency and material compatibility for real-world applications.

This research deals with the bacteriostasis and the skin-innoxiousness of a nanosize silver colloidal solution used as an agent for the antibacterial treatment of textile fabrics. We placed nanosize silver colloidal solutions and the textile fabrics treated with the same solutions on germ-containing agar plates, respectively, and calculated the bacterial reduction after certain contact times to evaluate the antibacterial efficacy of nanosilver in colloidal solutions and textile fabrics. The anti
Abstract Bicomponent sheath‐core fibers were prepared by a general melt‐spinning method with polypropylene chips and silver nanoparticles. The melt‐spun fibers were characterized by DSC, WAXS and SEM. The antibacterial effect was evaluated by an AATCC 100 test, a quantitative method. The results of the DSC thermogram and the intensity pattern of X‐ray diffraction indicated that the crystallinity of polypropylene including silver nanoparticles was slightly decreased compared with that of pure pol
Different nanostructures of TiO2 play an important role in the kinetics of dye sensitized solar cells (DSSC) and affect the overall light harvesting efficiency of the cells. This article describes that the one dimensional nanostructure of TiO2 (nanotubes) can increase the light scattering effect, light harvesting effect and electron transport in the DSSC to improve its performance. Pure anatase TiO2 nanotubes were synthesized by a hydrothermal method using commercial material (P25) due to which
Textile wearable electronics offers the combined advantages of both electronics and textile characteristics. The essential properties of these flexible electronics such as lightweight, stretchable, and wearable power sources are in strong demand. Here, we have developed a facile route to fabricate multi walled carbon nanotube (MWCNT) coated polyester fabric as a flexible counter electrode (CE) for dye sensitized solar cells (DSSCs). A variety of MWCNT and enzymes with different structures were u
