Electrochemical Evaluation of the Chitosan-Gelatin Biopolymer as a Detached Film with a Body Simulated Physiological Solution

Abstract

Biomaterials are being used in implants as metallic supports, to restructure bone and tissue in biomedical applications, and so forth. In this study, the assessment of films from the Chitosan-Gelatin system in detached condit ions was carried out, in order to evaluate the effect of the electrolyte over the mem brane, to simulate a physiological solution. An equivalent circuit is proposed, so as to interpret the process of biopolymer degradation using electrochemical parameters, as we ll as a reaction mechanism for the membrane’s cathodic areas. The gathered information may be associated with the biodegradability ionic diffusion behavior, also in its application as a temporary coating for metal protection control during the corrosion p rocess of biomaterials, such as magnesium, in bone regeneration.
