| description | This
paper approaches the study of pH’s effect on elaborate films of solid
biopolymer electrolyte from cassava starch and its impedantiometric response.
The films of solid biopolymer electrolyte were elaborated by thermochemical
synthesis while varying the pH (2, 4, 5, 7, 9, 10, and 12). Starch was
extracted from cassava tubers by a traditional method (disintegrated, washed,
decanted, filtered, and dried). Solid biopolymer electrolyte films were processed
by thermochemical synthesis by adding
plasticizers (glycerol, glutaraldehyde, and polyethylene glycol) and lithium
salt (lithium perchlorate). The impedance behavior was studied using the
electrochemical impedance spectroscopy technique. The
Nyquist and Bode’s diagrams registered presented a similar trend in all the
films; therefore, they were described by the same equivalent circuit model.
However, the equivalent circuit components presented different values in each
case. The conductivity and capacitance showed a quadratic polynomial tendency
in relation to the pH, obtaining the highest conductivity in the films
elaborated at acidic pH and the highest capacitance in the films elaborated at
basic pH. The degree of basicity or
acids allowed conductivity to be modulated or capacitance of the solid
biopolymer electrolyte as required. It could be concluded that the production
pH has a marked effect on impedantiometric behavior of films of solid
biopolymer electrolyte from cassava starch, which may be useful to modulate the
electrochemical properties of this type of material in future Applications. |
