| Abstract: | Three component polymeric thydrogels with greater water sorption properties were prepared of polyacrylamide, poly-vinylpyrrolidone, and gelatin by crosslinked polymerization method. The water uptake by hydrogel was greatly dependent on the composition of the hydrogel and external stimuli such as the presence of electrolytes and temperature of the system. The dynamics of the sorption process was investigated and found to be Fickian controlled. The hydrogels prepared were found to exhibit high antithrombogenic property than that possessed by the glass surface. |
