Pore Analysis for Transmission Electron Microscope Images of Activated Carbon Using Fuzzy Templates
抄録
Activated carbons are used, as absorbent materials, in various places. It so numbers of pores that the surface areas of them become very large. The analysis of the microstructure of the pores, especially regarding the shape or morphology of the pores, has not yet been adequately clarified. Generally we use transmission electron microscopy (TEM) images of them in order to analysis the property. TEM provides a very useful technique for analyzing porous materials, because it gives visual and detailed information about the pores. We have tried to use TEM of activated carbons, combined with image analysis, in order to make TEM a quantitative technique. It is important that the pore boundaries are clarified to analyze the pore structure, but extraction of the edges of pores is difficult by conventional techniques because of their irregular density sifts in the TEM images. In this work, we tried to extract of the pore boundaries of the activated carbons by using fuzzy template obtained from notion of a fuzzy phase, which was established as set with an ambiguous limit by the others. In this report we show the good result which was obtained by the experiments.
