The present work involves the Gum ghatti-cl-poly(NIPAm)/-o-MWCNT (GGNIPACNT) hydrogels via free radical polymerization technique. The synthesized hydrogels were characterized by FTIR analysis which suggested the successful binding of -o-MWCNT in to the hydrogels. This study explores the influence of oxidised multiwalled carbon nanotube (-o-MWCNT) content on the rheological and mechanical properties of Gum ghatti-cl-poly(NIPAm) hydrogels. To know their rheological behavior and processibility, we mixed oxidised multiwalled carbon nanotubes (-o-MWNT) in the hydrogel. Their rheological properties were measured with a cone and plate rheometer. It was found that as -o-MWNT the aspect ratio or concentration increased, the -o-MWNTs interactions became stronger as indicated by a higher storage modulus G, complex viscosity |*|, and steady shear viscosity . All hydrogels demonstrated shear thinning behavior and nanotubes showed statistically substantial arrangement in the direction of the shear flow. The flow curves of the hydrogel samples displayed non-Newtonian behavior. The flow profiles viscosity vs. shear rate were calculated through Power Law model, while the flow curves shear stress vs. shear rate were evaluated by applying the Herschel–Bulkley model where both the models were found to be best fitted model. Frequency-dependent rheological behaviors of nanocomposites in linear viscoelastic region indicated that the storage modulus (G), loss modulus (G), complex viscosity (|*|) increased with the increasing amount of -o-MWCNT. Linear viscoelastic measurements show that both complex viscosity and moduli increase with increasing -o-MWCNT concentration. Our results show that the mechanical properties of the composite hydrogels are considerably enhanced with increasing the content of-o-MWCNT. Therefore, these hydrogels may have probable applications in biomedical fields without the restrictions of water capacity and mechanical properties.
