Popis:	This work presents the results of studying hydrophobized silica gel Fluka 100 C8 + C1 with additional chemical surface modification by single-link alkylsilane. The material is studied by low-temperature nitrogen sorption and liquid porometry, including additional liquid porometry methods. The results of studying the system without additional modification are also presented. All results are presented for three temperatures: 20, 40, and 60°C. It is shown that additional chemical modification allows an increase in the fraction of the nonwetting liquid flowing from the pores with increasing temperature while maintaining a significant proportion of nonwetting liquid that has not outflowed under normal conditions. The obtained results show that, by additional modification, it is possible to control the process of the time relaxation of a nonwetting liquid in a nanoporous medium.
