摘要：

The surface free energy values for seven different controlled-porosity glasses were calculated from the adsorption data of n-octane and toluene. They were then correlated with specific surface area, mean pore diameter and total pore volume of these glasses. The analysis was performed assuming the capillary model. It was found that the surface free energy of the glasses increased considerably when the mean pore diameter increased from 35 to 63 nm. This was attributed to differences in the liquefaction process during preparation of controlled-porosity glasses characterized by various pore sizes.
