초록
In this research, poly(acrylic acid) (PAAc) hydrogels containing zinc oxide particle wereprepared by gamma-ray irradiation. PAAc powder was completely dissolved in distilled water atroom temperature. Water-insoluble zinc oxide powder were added into the PAAc solution andstirred until totally dissolved. Finally, the mixture was irradiated by gamma-ray irradiation tomake crosslinking. The effects of various parameters such as zinc ions’ concentration, irradiationdoses were varied and investigated in detail. PAAc hydrogels containing zinc oxide particle werecharacterized by gel content and swelling ratio. Moreover, the antibacterial properties of thismaterial were evaluated by paper diffusion test against the Gram positive and Gram negativebacteria.
