Function of NaOH hydrolysis in electrospinning ZnO nanofibers via using polylactide as templates

Highlights
- PLA was used as templates to electrospin ZnO nanofibers for the first time.
- Without NaOH hydrolysis, only ZnO film was prepared.
- Under function of NaOH, ZnO nanofibers were obtained.
- The function of NaOH was discussed.
- ZnO nanofibers showed much higher photocatalytical efficiency than ZnO film.
