Abstract

In this research, synthesis and evaluation of aluminium nitrate on the conductivity of hydrogel nanocomposite had been studied using acrylic acid monomer and single-walled carbon nanotubes. For this purpose, the water-based acrylic acid-based monomer was synthesized with optimal amounts to achieve a high-water absorption capacity of a hydrogel. The polymerization reaction was carried out in an aqueous medium by ammonium persulfate as initiator and methylene bisacrylamide as cross-linker. The hypothetical mechanism proposed for the formation of the hydrogel and its structure was confirmed by SEM and FTIR instruments. Then water absorption and swelling behavior in buffer solutions were examined. The results  show that the synthesized hydrogels in water absorption capacity and conductance and electrical conductivity of single-walled carbon nanotube has increased by the addition of aluminium nitrate and sodium phosphate, conductivity is improved and 19.60m/S .the next step, the swelling rate of the hydrogel was investigated in buffer solutions of 4 and 9 that in the basic medium was 0.921 /g.
