Abstract Studies were performed on silica gels synthesized in isopropanol to determine the parameters necessary to follow evaporative drying quantitatively, particularly during the last drying phase controlled by vapor diffusion in the gel nanostructure. As prepared and silanized gels were compared. Dynamic vapor sorption of isopropanol was used to determine adsorption isotherms and apparent diffusion coefficients in the silica network. A significant effect of surface modification (consisting… Expand
