Aggregation States and Degradation Behaviors of Thin Polyamide 4 Films |
| 초록 |
Polyamide 4 (PA4) has a great deal of attention as one of environment-conscious materials because of the synthesis from nature-based monomers and the degradability in underwater environments. However, the degradation mechanism of PA4 is not well understood even now. In this study, the aggregation states of thin PA4 films supported on solid substrates were examined by atomic force microscopy (AFM) and grazing-incidence wide angle X-ray diffraction (GI-WAXD) measurements. AFM revealed that the outermost surface of the PA4 films became rougher in water. GI-WAXD measurements made it clear that the crystal transition of PA4 was induced by water. It was found that the degradation in the underwater environment was relatively faster for the γ-form-rich PA4 film as an initial structure than that for the α-form-rich one. |
