SISTEMA EXPERIMENTAL INTERFACEADO PARA O ESTUDO DE FILMES ELETROCRÔMICOS

A system for measuring optical, mechanical and electrochemical properties of electrochromic thin film is described. The system comprises a computational interface and software that manages a potentiostat, which generates controlled potential and current signals, used to perform electrochemical intercalation of Li+ions and electrons il1tO lhe film. The interface also reads lhe electrical potenlial from oplical detectors used to 11Ieasurechange in lhe oplical transmittance and 11lechanicalstrain of lhe film caused by lhe electrochemical intercalation. Acquired data saved in ASCII files can befurther opened in data analysis software.
