Control of Degradation of Poly(l-lactide) by Surface Modification |
| 초록 |
In order to control the initial rate of enzymatic degradation, a The biodegradable poly(l-lactide) (PLLA) was modified by the incorporation of small amount of hydrophobic components which are inactive to enzyme as a degradation medium. The surface properties of modified cast films were investigated by Electron Spectroscopy for Chemical Analysis. The results showed that the surface layer of both modified PLLA films was dominated by the modifiers with lower surface free energy. The results showed a retardation of the initial enzymatic degradation of the modified PLLA films due to the surface segregation of modifiers. |
