Abstract

This research paper presents the novelty of a new Na-Bentonite-graft-acrylamide/acrylic acid superabsorbent composite material that has high water absorbency and whose graft ratios were established by graft-copolymerizing acrylamide, acrylic acid, and Sibi Bentonite together in an aqueous solution. Fourier Transform Infra-Red Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and a Thermogravimetric Analyzer (TGA) were employed to determine the shape, thermal stability, graft copolymerization reaction process, and the effects of Na-Bentonite content, initiator concentration, and grafting ratio on the water absorbency of these composite materials. According to the findings, clay concentration increased while water absorbency showed a decrease. FTIR analysis confirmed the presence of acrylamide/acrylic acid on the backbone of clay. TGA data indicated an increase in thermal stability of the sample with the addition of Sibi Bentonite to the polymer network. The SEM results showed the grafting of acrylamide and acrylic acid onto clay. The cross-linking agent Sibi Bentonite in the form of ultrafine mineral powder is crucial in the development of the superabsorbent composite's network structure.
