Nasrine Boughezala: Please provide more information on your protocol, e.g. did you evacuate the solvent (NMP is notoriously hard to remove from polymer solutions), what concentration and source of PANI did you use, what type of glass substrates are you using and whether the glass was pre-treated in any way?

To create adherent polyaniline thin films on glass, prepare a well-dissolved aqueous solution of aniline with a strong acid, and clean the glass substrate thoroughly. Use deposition methods like spin or electrochemical coating, and consider doping and curing to enhance film quality and adhesion.

Abdelhak Maghchiche Thank you so much
