| degradability_notes |
PET nano fibres undergo slow hydrolysis; surface area-to-volume ratio enhances degradation rate relative to microfibres. |

| detection_method_notes |
PET at the nanoscale is challenging to detect. KOH digestion may eliminate PET nano-fibres. SEM-EDX can identify by elemental composition but polymer confirmation requires Nano-FTIR. |
