Comparison of pore analysis techniques of the paper

종이의 Pore 특성 측정 기법의 비교

The best way to understand paper properties is to study paper structure. Paper is composed solid materials (pulp and other additives) and air three-dimensionally, it's important to understand pore structure of the paper. There are several method to analysis pore structure of the paper. Mercury intrusion technique is frequently used for the characterization of the porous paper, giving access to parameters such as pore size and pore distribution. But some researchers indicated mercury intrusion distorts the structure due to application of high pressure. So this paper suggest new analysis technique to pore structure of the paper. New pore analysis technique with SEM does not require high pressure, gives good resolution and measures pore structure.
