文摘
- •
Thermoplastic polyurethane (TPU) nanocomposites exhibit a multi-scale phase separation morphology.
- •
Carbon nanotubes (CNTs) effectively influence the TPU morphology at different scales.
- •
CNTs preferentially aggregate in the TPU hard domain (HD) regions.
- •
CNTs favor nucleation and growth of smaller and more distributed HD spherulites.
- •
Cellulose nanocrystals (CNCs) have a positive effect on CNT dispersion and distribution.
