Abstract

Porous media is used in many areas of applied science and engineering and its characterization of porosity and micro-structure is very important, therefore, it is very necessary to know the measurements of pore structure of porous materials. In this study, some traditional methods that are used to measure micro-structure of porous material were briefly introduced in this study, including mercury porosimetry method, gas adsorption method, electronic microscope method, small angle X-ray scattering method and bubbling test method, followed by some emerging technology, including the combination of different methods, medical imaging technology and image processing software. Meanwhile merits and drawbacks as well as the existing problems of methods mentioned were analyzed and application range was described. At last, the developing trends and prospect of newly emerging methods, which is used to measure micro-structure of porous material, are also described briefly.
