Characterization of aqueous natural polymersolution irradiated by gamma ray |
| 초록 |
The natural polysaccharides such as cellulose, hyaluronic acid, chitosan, alginate are soluble in water. Due to the unique biological, chemical and physical properties, these polysccahrides havemany industrial applications in various fields. In this study, carboxymethyl cellulose (CMC) and water soluble chitosan (WCh) was prepared aqueous solution and degraded by gamma ray irradiation. The changes in molecular weight were monitored by GPC measurements. Based on FTIR spectra,before and after degradation it was revealed that degradation undergoes by the breakage of the glycosidic bonds of polymers. |
