Activated carbon fibers (ACF's), already used widely as absorbent materials, are now expected to be useful as new electrical and electronic materials, for their very large specific surface areas (SSA). Chemical adsorption as well as x-ray diffraction have been mainly used for characterizing the ACF structure. While TEM observations reveal the texture of ACF's, such observations have not yet yielded quantitative information about the microstructure. To promote the quantitative interpretation of the TEM images, computer image analysis is used in this work to clarify the pore structure of ACF's. The microstructures of three samples, which are all isotropic pitch-based ACF's but with different SSA values, have been investigated. Operations such as noise reduction, low frequency cut-off filtering, and binary image formation are used to clarify the pore images of the ACF's. The distribution of the ACF porosity size is clearly shown by a frequency analysis of the two-dimensional fast Fourier transform (FFT). The results suggest that TEM images include contributions from many different pore sizes. Pores in different size ranges are extracted by the inverse FFT (IFFT) operation by selecting the specific frequency range, and by-this analysis the pore structure is shown to have fractal characteristics.

The activated carbon fiber(ACF) electrodes were prepared for electrosorption desalination. The electrodes were analyzed using scanning electron microscope (SEM), and the desalting efficiency was represented by the removal rate of Cl-. As a result, desalting efficiency decreases with increasing initial concentration of Cl-, whereas the total adsorption capacity increases. The most suitable voltage for electrosorption desalination is 1.2 ~ 1.4V. The electrosorption desalination achieves the best results while the distance between two electrodes is 1.0cm. Electrosorption plays a more important role in the adsorption process compared with physical adsorption. The removal rate of Cl- is obviously improved by using ACF electrode modified by HNO3 and KOH and desalination ratio of the electrode treated with KOH is increased by 16.5%. Therefore, the ACF electrode would be suitable for using in the application of electrosorption desalination.
