Scanning electron microscope images of cross-section of (a) 250H, (b) 1000E250H, (c) 2000E250H, and (d) 3000E250H, respectively, after carbonization at 1000°C. Fig. 5. Tensile strength and Youngs modulus of carbon bers prepared from pitch bers stabilized by using heat and electron beam. ..PAGE:6 Carbon Letters Vol. 16, No. 2, 121-126 (2015) DOI: http://dx.doi.org/10.5714/CL.2015.16.2.121 126... Carbon fibers are prepared by stabilizing pitch fibers accompanying electron beam (E-beam) irradiation. The carbon fibers pretreated by E-beam irradiation achieve a higher stabilization index than the carbon fibers that are only heat-stabilized. In addition, the carbon fibers subjected to E-beam irradiation in the stabilization step exhibit a comparable tensile strength to that of general purpose carbon fibers. The carbon fibers pretreated with an absorbed dose of 3000 kGy have a tensile... -

pitch fbers are shown in Fig. 4. The average diameter of melt-spun fbers without applied voltage was 10.2 ± 2.8 μm, and these fbers had a wide distribution compared to melt electro-spun fbers according to the applied voltage (5 kV: 8.5 ± 1.7 μm, 10 kV: 6.9 ± 1.3 μm, 20 kV: 4.7 ± 0.9 μm), as observed in SEM images. It is presumed that Fig. 3. Scanning electron microscope images of (a)... Spinnable pitch for melt-electrospinning was obtained from pyrolized fuel oil by electron beam (E-beam) radiation treatment. The modified pitch was characterized by measuring its elemental composition, softening point, viscosity, molecular weight, and spinnability. The softening point and viscosity properties of the modified pitch were influenced by reforming types (heat or E-beam radiation treatment) and the use of a catalyst. The softening point and molecular weight were increased in... -

4 (2010) 343-346 and the microstructure of various EGs was observed by scanning electron microscope (SEM, 3500N, Hitachi Science System Ltd., Japan). The electrodes were prepared by mixing 93 wt.% of the anode active materials and 7 wt.% of polyvinylidene fluoride (PVDF) binder dissolved in 1-methyl-2-pyrrolidinone (NMP) with a homogenizer at rotation speeds of 4000~5000 rpm to form slurry. The... -

image analysis was used. Transmittance Electron Microscope (TEM) is one of the most powerful apparatus to investigate the morphology of nano-scale. Moreover, it was confirmed that TEM is of use apparatus to observe the pore dimension by J. R. Fryer in 1980 [26]. Fig. 13(a), (c), (e) shows high-resolution TEM image and the corresponding pore size distributions of PVDC-base carbon samples, VESC, in... -
