Study of hydrophobized mesostructured material MCM-41-C1 by gas adsoption and liquid porometry methods

Resumo

Nanoporous mesostructured material MCM-41 and hydrophobized MCM-41 (MCM-41-C1) are studied by methods of gas adsorption, liquid porometry, and additional methods of liquid porometry. The additional methods applied are the partial filling of a porous medium with a nonwetting liquid and analysis of the time relaxation of the nonwetting liquid in the porous medium. The difference between the results given by methods characterizing the materials and the specific features of the interaction between the surface of the porous medium and the nonwetting liquid is shown.
