Local demixion in plasticized polylactide probed by electron spin resonance

- ESR technique to assess microphase separation or heterogeneities in plasticized PLA.
- Probing the chain mobility and microphase separation along the film thickness.
- Equivalence time/spatial scales in diffusion phenomena to get spatial resolution.
- Reconstruction of temperature profile along the PLA film thickness.
- Measured excess temperatures related to local shifts in the Tg along the film thickness.
