Abstract
AbstractThe electrodeposition of poly(3,4‐ethylenedioxythiophene) (PEDOT) for development of latent fingerprints on brass cartridge cases may be successfully performed, even though the simultaneous corrosion process of copper and zinc from the brass surface occurs. PEDOT is electrodeposited by direct oxidation of the monomer in aqueous LiClO4 solution using chronoamperometry (potentiostatic method) with experimental conditions set at 0.90 V versus Ag/AgCl and 180 seconds. Such strategy is interesting for application in forensic biometrics for development of latent fingerprints on brass cartridge cases, since it affords images with high definition, allowing a clear visualization of the ridge patterns and singular points, besides to be useful for confrontation in fingerprint databases. Therefore, this is a simple, efficient, fast, low‐potential, and low‐cost methodology for the processing of cartridge cases.
