Dear Shoubhik:

You will be helpful to choose a surfactant after the analysis of articles on the wettability of PET surfactants and alcohol solution. Koll. Z. 1966. Bd.211. N1-2. 84-93. J. Phys. Chem. 1959. V.63. N.11. 1241.

Best regards.

We can improve the surface energy of PET substrate by silane modification. This change enhances the adhesion.

Do spin coating in different steps. By reducing the acceleration of spin coating, we can avoid the complete spill of PVA solution in the initial steps.
