Abstract

The infiltration of glycerin in a lyophobic nanoporous silica gel is investigated experimentally, and the effective interfacial tension and viscosity are discussed. While the simple superposition principle can be employed for the analysis of interfacial tension, in a nanopore the effective liquid viscosity is no longer a material constant. It is highly dependent on the pore size and the loading rate, much smaller than its bulk counterpart. © 2008 American Institute of Physics.
