Hak-Yong Kim Ph.D., Professor Chonbuk National University, South Korea
Hak Yong Kim, a professor of BIN Convergence Technology Department in Chonbuk National University, South Korea. He received a B.S. degree from the Department of Textile Engineering of Chonbuk National University (South Korea) in 1981. He received his M.S. degree in Textile Engineering from Seoul National University in 1983. Then he received his Ph.D. degree from same University in 1993. From 1993 to 1998, he worked at Fiber Research Division in Samyang Group R&D Center. He became a professor at Chonbuk National University in 1998. He was made Director of Center for Healthcare Technology & Development of Chonbuk National University in 2004. Meanwhile, he was a visiting Professor at University of Massachusetts (USA) in 2004 and King Saud University (Saudi Arabia) in 2010, respectively.
His research interests center on biomaterials, polymer composites, inorganic materials, and carbon nanofibers. His main achievements include 338 published SCI journal papers with more than 9026 citations, H-index is 48 and 102 patents. He also received Jang Young Shil Award of Ministry of Science and Technology (1997), Academy Award of the Chonbuk Textile Engineering (2001), Excellence Award of the Chonbuk Textile Engineering (2002), Best Professor Academy Award of Chonbuk National University (2007, 2008), Medi Tex Award of Korea Fiber Society (2013), Grand Prize of Research Achievements of Chonbuk National University (2014) and Best Paper Award of Chonbuk National University (2008, 2012, and 2013).
报告大纲:
We report on the preparation and characterization of core–sheath structure of composite nanofibers by using electrospinning process. The morphology, chemical compositions, structure and thermal properties of the resultant products were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectrometer (EDX), high-resolution transmission electron microscopy (HR-TEM), Fourier transform infrared (FT-IR) spectroscopy, differential scanning calorimetry, thermogravimetric analysis (TGA) and X-ray photoelectron spectroscopy (XPS) techniques. The blending ratio of Core polymer and Sheath polymer, molecular weight of polymer and the applied voltage of electrospinning process were observed to be the key influence factors on the formation of core–sheath nanofibers structure. Bicomponent nanofibers increases the weight and strength than the single-component fibers. Therefore, It can be applied the separation, sensors, catalyst, bio, electronic devices, etc to various fields.
