Construção de uma célula espectroeletroquímica termostatizada e sua aplicação para estudar polímeros eletrocrômicos

The construction of a temperature controllable spectroelectrochemical cell is described. Its use in the analysis of the thermodynamic and structural parameters of the electrochromic process of poly(3-methyl thiophene) in the temperature range between -40ºC and 60ºC is given as an example of application.
