Abstract:
The aim of the present work is to prepare adhesive, mechanically strong and biocompatibleacrylamide and gellan gum based associated hydrogel. The tannic acid and MBA were utilized as a physical and chemical cross-linkers respectively to investigate the cross-linker nature on the adhesive performance of hydrogel. The hydrogel was synthesized by free radical polymerization method. The synthesis and surface morphology of hydrogels were confirmed by FTIR and SEM analysis respectively. Complete rheological tests were performed by rheometer (Anton paar) to check the adhesive behavior of the asprepared hydrogels. The results revealed that the interaction between polymer chains plays important role in controlling the adhesive behavior of hydrogels. The adhesion properties of the materials were tested by changing the amount of tannic acid (0.005 g to 0.020g) and it was found that the adhesion is first increase and then decrease. The rheological investigation via frequency sweep curve (shear measurement), creep recovery compliance test and amplitude sweep (dynamic mechanical analysis) were performed at different temperature 20, 30 and 40 °C. The storage (G') and loss (G'') moduli as a function of angular frequency, yield stress, tangent loss, damping factor and retention property were also studied to confirm the visco-elastomeric nature of the co-polymer p (AAm-co-GG). Our prepared adhesive hydrogel shows best performance towards glass, wood, ceramics and steel like materials.
