In the present study, exfoliated graphite nanoplatelets (xGnP) with different particle sizes were coated onto polyacrylonitrile-based carbon fibers by a direct coating method. The flexural properties, interlaminar shear strength, and the morphology of the xGnP-coated carbon fiber/phenolic matrix composites were investigated in terms of their longitudinal flexural strength and modulus, interlaminar shear strength, and by optical and scanning electron microscopic observations. The results were... -

for 1-4 h using potassium hydroxide (KOH) powder as the activation agent. The optimal activation conditions were determined to be a CTP/KOH ratio of 1:4, activation temperature of 900°C, and activation time of 3 h. The obtained ACs showed increased pore size distribution in the range of 1 to 2 nm and the highest specific capacitance of 122 F/g in a two-electrode system with an organic electrolyte, as measured by a charge-discharge method in the voltage range of 0-2.7 V. In order to improve the... -

Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs.... -

본 연구에서는 청정 호발공정의 하나로 플라즈마 처리를 사용하였다. 폴리에스테르(polyethylene terephthalate, PET) 직물에 가호된 폴리비닐 알콜(polyvinyl alcohol, PVA), 아크릴 호제(polyacrylic acid esters, PACL)과 이들의 혼합된 호제들을 질소($N_2$)와 산소($O_2$) 플라즈마로 처리하였다. 호제제거에 있어서 산소 플라즈마가 질소 플라즈마 보다 더 효과적이었으며, PACL 보다는 PVA 호제 제거가 더 우수하였다. 플라즈마 처리된 시료의 주사전자현미경(scanning emission microscopy, SEM) 사진을 통하여 호제들이...
