Effects of pore structures on electrochemical behaviors of polyacrylonitrile-based activated carbon nanofibers by carbon dioxide activation
Hye-Min Lee, Hong-Gun Kim, Kay-Hyeok An, Byung-Joo Kim 한국탄소학회 Carbon Letters 6 Pages

Activated carbon nanofibers (ACNF) were prepared from polyacrylonitrile (PAN)-based nanofibers using CO2 activation methods with varying activation process times. The surface and structural characteristics of the ACNF were observed by scanning electron microscopy and X-ray diffraction, respectively. N2 adsorption isotherm characteristics at 77 K were confirmed by Brunauer-Emmett-Teller and Dubinin-Radushkevich equations. As experimental results, many holes or cavernous structures were found on... -
Hierarchical porous carbon nanofibers via electrospinning
Aikifa Raza, Jiaqi Wang, Shan Yang, Yang Si, Bin Ding 한국탄소학회 Carbon Letters 14 Pages

(CNFs) with diameters in the submicron and nanometer range exhibit high specific surface area, hierarchically porous structure, flexibility, and super strength which allow them to be used in the electrode materials of energy storage devices, and as hybrid-type filler in carbon fiber reinforced plastics and bone tissue scaffold. Unlike catalytic synthesis and other methods, electrospinning of various polymeric precursors followed by stabilization and carbonization has become a straightforward and... -

본 논문은 열경화성수지 적층 복합재료의 낮은 충격 특성과 층간 분리 현상을 개선하고자 열가소성 수지 및 3차원 직조 프리폼을 사용한 복합재료 제조와 물성 특성화에 대한 것이다. 새로운 기술인 co-braiding 성형법으로 열가소성 PEEK 섬유와 탄소섬유를 혼합한 섬유를 제조하였으며. 층간 분리 억제 특성을 현저하게 향상시키기 위하여 두께방향의 섬유를 가지는 3차원 직조형 프리폼을 제조하였다. 혼합섬유로 제조된 프리폼에 열성형 공정을 적용함으로써 열가소성 복합재료를 제조하였으며. 혼합섬유의 PEEK 섬유는 용융온도에서... -
