SYNTHESIS AND CHARACTERIZATION OF SUPERABSORBENT HYDROGEL BASED ON SUGARCANE BAGASSE GRAFTED ONTO POLYACRYLIC

Abstract

Superabsorbents hydrogel were prepared by grafting of sugarcane bagasse on polyacrylic acid by using N, N \-methylene bisacrylamide as cross-linker and ammonium persulphate as initiator. Factors such as weight ratios of bagasse and acrylic acid monomer that affect the properties of the product were investigated. Properties of superabsorbent such as water uptake, gel fraction,morphological structure and thermal properties were also examined.
