Nanomechanical properties of poly(l-lactide) nanofibers after deformation

- PLLA nanofibers produced by TIPS method have a multi-level structure.
- Use AFM nanolithography to produce deformation on individual nanofiber.
- Structural variation has a direct functional consequence in the nanomechanical properties.
- Polymer chains become more compact and ordered caused by both compressional stress and shear stress.
