A Geant4 simulation study on radiation induced PLCL films as degradation models |
| 초록 |
In this study the degradation behavior of poly(L-lactide-co-ε-caprolactone) (PLCL) was investigated under depending on the level of gamma-ray irradiation and preliminary compared with Geant4 simulation study. Exposure to gamma radiation reduced the average molecular weight (Mn and Mw), and weakened mechanical strength, because it affects the hydrolysis factor and reduces stability. The degradation patterns with Geant4 simulation were obtained after calculating the changes of number-average molecular weight. In conclusion, the predicted results showed a similar tendency to the results of the experiment carried out in this study. |
