I wanted to know the best way to measure or at least compare the amount of PEDOS:PSS coated on a PCL film.
Hi,
Deposit your coating using the same condition on a planar surface, i.e. a si wafer by blocking a part of it. Then, after coating, you can measure the thickness by contact profilometry by establishing the non-deposited part as your baseline.
Good luck!
The performance of multilayer films of PEDOT:PSS treated with trifluoroacetic acid has improved the sheet resistance and conductivity, leading to the development of more effective transparent electrodes.
Overall, PEDOT:PSS film characteristics are strongly influenced by the substrate temperature during printing and annealing temperature as well as surface modification, determined by a mix of surface wetting characteristics, rate of evaporation of the solvent and coalescence of the printed lines.
