ESTUDO ESPECTRO ELETROQUÍMICO DE SISTEMAS ESTRUTURADOS ARGILA-CORANTE
| Resumo: | The eletrochemical and espectroelectrochemical behavior of the montmorilonita methylene-blue system (MM-AM)/ AMsolution have been investigated using cyclic volta mmetry and transient (I x t) techniques on modified ITO glass electrodes by film of composite (MM-AM) mechanically deposited. These films were prepared by three way: 1- in the absence of surfactant CTACl (cetyltrimethyl-ammonuim chloride); 2- with incorporation of CTACl into the interlayer region; and 3- in the presence of CTACl, however, not incorporated into the interlayer region. The spectroelectrochemistry technique was used for characterization and study of the formed films. The experimental results allowed assumptions as follows: 1- films prepared with AM previous incorporated into interlayer region supply a more efficient electrochemistry answer with the appearance of a couple of well defined peaks; 2-CTACl, in general, allows to obtain mechanically stable films; 3- when CTACl is previously included into interlayer region it doesn’t exist intercalated protonated specie, AMH+; 4- when protonated specie is absent the composite doesn’t shows electrochromic behavior. |
