The effect of a gamma-ray irradiation on the formation of silver nanoparticle in the crosslinked carboxymethyl cellulose |
| 초록 |
Silver nanoparticles(AgNPs) possess a peculiar anti-bacteria performance besides the excellent properties owned by metal nanoparticles. The effect of a gamma-ray irradiation on the formation of AgNP in the crosslinked carboxymethyl cellulose(CMC) was investigated. A CMC generally contains a relatively large amount of sodium salt. The CMC solutions were irradiated for the crosslinking at room temperature with different doses of gamma ray, and then the silver nitrate (AgNO3) were added in the crosslinked CMC for the formation of AgNPs. The morphologies of AgNPs in the crosslinked CMC were observed by a scanning electron microscopy (SEM). The UV data apparently showed the characteristic band at 410-440 nm for the existence of AgNPs in the crosslinked CMC. |
