Parameter for PVDF-TrFE spin coating
As expected, a faster spin speed and longer spin time resulted in a thinner film.

Spin coating
Spin coating is a procedure to deposit a thin coating material onto the sample uniformly. Different speed were used to characterize the film thickness. A polymer concentration of 5 wt% was determined to be ideal. Samples were prepared using a 10wt% solution, but the solution was very viscous and resulted in very rough films.
