CHARACTERIZATION OF SWELLING BEHAVIOUR OF NANOCLAY COMPOSITE

Abstract

Water sorption capacity is an important characteristic for nano clay composite (NCC) super absorbents especially when used under rainfed condition. The Zn coated nano clay composite cross-linked polyacrylamides polymers were synthesized by polymerization reaction with 10% acrylic acid, acrylamide, 0.9% ammonium persulphate as initiator, 0.12% N, N/ methyl biscrylate as cross linker loaded with 8% benitonite clay and 10 % Zn citrate at 650C reaction temperature. The water absorbency of product had 165.7 g/g in tap water, 183.0 g/g in distilled water and 74.3 g/g in 1% NaCl solution. Water-holding capacity of the soil with NCC was 8.5% more as compared to original soil.
