dc.description.abstract | Super absorbent polymer (SAP) sorbs copious amount of liquid water but its sorption power for water vapor is quite low. On the other hand, mesoporous silica loaded with CaCl2 (MPS-CC) has high sorption capacity for water vapor. However, this is determined by the salt loading, which is limited due to its corrosiveness. Even by simple powder blending of 75 mass% of SAP and the balance of MPS-CC (SAP75/MPS-CC25), the 3-hour maximum specific water uptake (g H2O/g sorbent) reached the maximum, 3 times the equilibrium uptake of MPS-CC. The sorption property was further enhanced by developing a new sorbent in which mesoporous silica was grown on the surface of swelling SAP and then impregnated by CC in ethanol. In the new sorbent (SAP-iMPS-CC), MPS grew organized, straight and lengthwise by the help of SAP. Owing to such intimate contact between MPS and SAP, the 3-hour specific water uptake of the new sorbents grown for more than 24 h (SAP-iMPS-CC24) was kept constant at the value of 2 times that of SAP75/MPS25. The SAP mass% of SAP-iMPS-144 could reach 25 without the sacrifice of sorption capacity. | - |
