Self-assembled aromatic polyamide nanofibers with trifluoromethyl groups via precipitation polymerization

- Aromatic polyamide nanofibers with trifluoromethyl groups were prepared.
- The nanofibers showed a strong interaction with the reaction solvent to form a gel.
- Many small particles aggregated to form nanofibers.
- The morphology and characteristic features depended on the reaction period.
