Effects of maleic anhydride content on mechanical properties of carbon fibers-reinforced maleic anhydride-grafted-polypropylene matrix composites
Hyun-Il Kim, Woong Han, Woong-Ki Choi, Soo-Jin Park, Kay-Hyeok An, Byung-Joo Kim 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 6 39-46 (8 pages)
In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared... -
Preparation of gold nanoparticle/single-walled carbon nanotube nanohybrids using biologically programmed peptide for application of flexible transparent conducting films
MinHo Yang, Bong Gill Choi 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 4 26-31 (6 pages)
In this study, we report a general method for preparation of a one-dimensional (1D) arrangement of Au nanoparticles on single-walled carbon nanotubes (SWNTs) using biologically programmed peptides as structure-guiding 1D templates. The peptides were designed by the combination of glutamic acid (E), glycine (G), and phenylalanine (F) amino acids; peptides efficiently debundled and exfoliated the SWNTs for stability of the dispersion and guided the growth of the array of Au nanoparticles in a... -
Flexural properties, interlaminar shear strength and morphology of phenolic matrix composites reinforced with xGnP-coated carbon fibers
Jong Kyoo Park, Jae Yeol Lee, Lawrence T. Drzal, Donghwan Cho 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.17 No.1 5 33-38 (6 pages)
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... -
Effect of nitrogen doping and hydrogen confinement on the electronic properties of a single walled carbon nanotube
Bashir Mohi Ud Din Bhat, Jehangir Rashid Dar, Pratima Sen 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2016, Vol.17 No.1 4 29-32 (4 pages)
This paper addresses the effect of dopants on the electronic properties of zigzag (8, 0) semiconducting single walled carbon nanotubes (SWCNTs), using extended H?ckel theory combined with nonequilibrium Green’s function formalism. Through appropriate dopant concentrations, the electronic properties of SWCNTs can be modified. Within this context, we present our ongoing investigation on (8, 0) SWCNTs doped with nitrogen. Quantum confinement effects on the electronic properties of the SWCNTs have... -
Micro-sized carbon with dimple patterns prepared using an electro-spray method
Mi-Seon Park, Young-Seak Lee 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.3 9 215-218 (4 pages)
Carbon micro particles with dimple patterns were produced by electro-spraying a solution of pitch in tetrahydrofuran. Particle formation depended on separation in an electrical field and volatilization of the solvent. More than 80% of the obtained carbon exhibited an average particle size of less than 50 μm. X-ray diffraction analysis suggests that the carbon with dimple patterns has increased crystallinity after heat treatment. -
Preparation of sulfonated reduced graphene oxide by radiationinduced chemical reduction of sulfonated graphene oxide
Chang-Hee Jung, Ji-Hyun Hong, Jin-Mook Jung, In-Tae Hwang, Chan-Hee Jung and Jae-Hak Choi 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 6 41-44 (4 pages)
We report the preparation of sulfonated reduced graphene oxide (SRGO) by the sulfonation of graphene oxide followed by radiation-induced chemical reduction. Graphene oxide prepared by the well-known modified Hummer's method was sulfonated with the aryl diazonium salt of sulfanilic acid. Sulfonated graphene oxide (SGO) dispersed in ethanol was subsequently reduced by γ-ray irradiation at various absorbed doses to produce SRGO. The results of optical, chemical, and thermal analyses revealed that... -
