RELAXATION OF A NONWETTING LIQUID DISPERSED IN A PARTIALLY FILLED NANOPOROUS MATERIAL

The authors have given results of experimental study of metastable states of a nonwetting liquid (distilled water) dispersed in the pore space of hydrophobizated silica gel Fluka 100 C₁₈ under the conditions of partial fi lling. The results were obtained for 10 and 22^o C with a varying degree of fi lling (11 to 100%) at expectation times from 1 to 1000 s. According to the obtained data, the dependence of the fraction of fast states on the initial degree of fi lling has been obtained at diff erent temperatures. It has been shown that the increase in temperature and the increase in the initially fi lled fraction of the volume of nanoporous material lead to a growth in the fraction of fast states with a characteristic time of outfl ow of the order of several seconds.
