抄録
The porosity and water vapor sorption property of commercially available hydrophobic SiO2beads were investigated. The hydrophobic SiO2 beads, the surface of which has been modified by trimethylsilyl functional groups, with a surface area of 70.7 m2/g, a mesopore diameter of about 36 nm and a mesopore volume of about 0.91 cm3/g showed lower water vapor sorption property as compared to the unmodified SiO2 beads; the amount of monolayer water adsorbed were estimated to be 2.94×10-3 and 5.12×10-3 g(H2O)/g(adsorbent) for hydrophobic and unmodified SiO2 beads, respectively. The evaluation of the heat of water vapor sorption suggests that the suppression of water cluster formation by trimethylsilyl groups is attributed to the hydrophobic property.
