| Abstract:
The present work is including synthesis and characterization of conductivity of a super-absorbent conductive hydrogelnanocomposte and its controlled drug release. For this purpose, superabsorbent conductive hydrogel by Guar gum was synthesized based on grafting copolymerization of acrylic acid monomer and proximity of some carbon nanotubes; in addition, polymerization reaction was done in aqueous phase (distilled water) and in the presence of ammonium persulfate as initiator and Methylene bisacrylamide as cross-linked. The results were assessed by FT-IR, cyclic Voltammetry and Scanning Electron microscope. However, the effect of carbonnanotube’ s amount on nanocomposite was characterized by increasing this amount, the gel content, equilibrium swelling in distilled water, pH sensitivity, and conductivity increases. In the second stage, cisplatin drug was loaded in hydrogelnao composite and the percentage of drug release in phosphate buffer solution (PBS) was measured by appropriate electrical stimulation. The results show that the synthesized hydrogel is reasonable option for controlled drug release.
