Abstract

IN THIS STUDY, polyvinyl alcohol (PVA) and poly (N-vinyl-2-pyrrolidinone) (PNVP) hydrogels were prepared by two techniques of irradiation; ultrasound and gamma rays, respectively in purpose of comparative study. The formed hydrogels from both approaches were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry, (DSC), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray spectroscopy (XRD), hardness and inductively coupled plasma optical emission spectroscopy ((ICP-OES). Moreover, the swelling behavior and gel faction were studied for the produced hydrogels of both approaches. The results indicate that hydrogels were prepared by both approaches are having the similar physical and chemical properties. The hydrogels formed were used in the ionoprinting technology. The ionoprinting technology has ability to topographically structure and actuates hydrogels by locally patterning ions via complexation assisted by electric fields. The significant features of ionoprinted hydrogels are stable for 36 days. Further, the ionoprinting process is fully reversible by immersion the ionoprinting hydrogels into a chelator.
