The effect of heat treatment on the surface structure of polyaniline nanostructured film: An experimental and molecular dynamics approach

- We study the surface structure of PANI nanostructured films based on the roughness parameters obtained by AFM analysis and Molecular dynamics approach.
- In the Tg ≤ T < Tm range, film shows an increase in surface roughness.
- In the T < Tg range, film exhibits a smooth surface.
- A scheme for height correction relying on optical profilometer was employed for compensation of errors in determination of surface roughness.
- The expected power law behavior was confirmed experimentally and computationally.
