| Abstract | In this study, the hydrogels composed of polyvinylpyrrolidone (PVP), kappa-carrageenan (kappa C), and 1,2-hexanediol (HD) were prepared by gamma-ray irradiation. The radiation dose was 25 kGy and the concentration of kappa C was 3 wt%. The physical properties of the hydrogels were investigated as a function of the concentrations of PVP and HD. The gel content and the tensile strength increased with increasing PVP concentration due to the crosslinking between the pyrrolidone molecules and decreased with increasing HD concentration. The degree of swelling was inversely proportional to the gel content because the highly crosslinked hydrogels had a tighter structure, hence reducing their water absorption. The antibacterial tests indicated that the hydrogels containing HD had antibacterial activity. |
