Etching Electrode from Piezo PVDF Film, PolyK USA

Описание: While we offer piezo PVDF film with electrode with size from paper size to roll of 100 m long :

customers will need to cut the film to different sizes to produce their own sensors and actuators and speakers. The film can be easily cut with sharp scissors or razor blade, though sometime the top and bottom electrode may touch each other at the cutting edge and lead to electrical short circuit (particularly for thin film). Customers can etch the electrode along the cutting edge easily following this video to avoid this short circuit issue:

A. Sputtered copper can be etched by Ferric Chloride [FeCl3] aqueous solution
B. Aluminum can be etched by HCl, KOH, NaOH dilute aqueous solution
C. ITO can be etched by dilute HCl aqueous solution
D. Thick printed silver electrode can be carefully removed by acetone.
E. Sputtered Cu/Al/Gold can be removed by a high-current burning process (email us for instructions):    • Quick Etching Cu/Ni Electrode on Piezo Fil...  
F. Sputtered Cu/Al/Gold can be removed by ultrafast UV laser (nanosecond or faster to avoid heat transfer to PVDF). By adjusting laser power, you can remove the non-transparent electrode without damaging PVDF (transparent).
G. Dry film photolithography can also be used to pattern your sensors.
