Abstract
A superabsorbent composite was synthesized via polymerization in a complete aqueous environment. A polymeric composites was fabricated effectively by varying the concentration of natural gum and crosslinker. Reinforcing of the polymer chains with bentonite sheets was confirmed by Fourier transform infrared (FTIR) spectra. X-ray diffraction (XRD) revealed that bentonite was exfoliated and dispersed in the polymeric matrix. Scanning electron microscopy (SEM) and thermal analysis (TGA/DSC/DTA) were used to study the morphology and thermal stability of the composites, respectively. The effects of natural gum and crosslinker were investigated. Results showed that introducing organic-inorganic composites improved the swelling capability and water retention ability of the superabsorbent.
