英文摘要	In this study, the application of superabsorbent resin (SAP) in inhibiting the soil moisture evaporation (or slowing down the water outflow) was studied. The clay-SAP composites were fabricated by grafting of poly (acrylic acid-N-hydroxymethyl acrylamide/clay) (GT-g-P [AA-co-NHA]/clay) on Tragacanth gum (GT), using solution polymerization. The structure, morphology and stability of the clay-SAP composites were investigated by Fourier transform infrared, scanning electron microscope and TGA. The maximum swelling ratio of Attapulgite (3%)-, Kaolin (3%)- and Montmorillonite (3%)-SAP composite in deionized water reached 1180, 819 and 525 g/g respectively, and the maximum swelling ratio in tap water reached up to 206, 192 and 170 g/g respectively. Meanwhile, the maximum swelling ratio in 0.9% NaCl solution was 95, 82 and 62 g/g respectively. The water retention of clay-SAP composites was also analyzed as a function of temperature. In addition, by simulating the desertification area, the effect of the APT (3%)-SAP composite on the anti-evaporation performance was studied. The obtained results revealed that the water retention of APT (3%)-SAP composite was 36% at 45 degrees C for 12 h. Under natural conditions, the evaporation rate of the anti-evaporation material was inversely proportional to the amount of APT (3%)-SAP composite added.
