Abstract
The influence of three different solvents including lactic acid, formic acid, and acetic acid on the constant-voltage electrodeposition behavior of chitosan biopolymer was investigated. In this regard, charge density, viscosity, and some molecular parameters of chitosan solutions in aqueous acids were studied. The mechanism of chitosan film formation was investigated by fitting the current density–time experimental data to the Pierce and Miskovic film growth models. It was found that solvents have a significant influence on the molecular structure and electrodeposition behavior of chitosan. Using formic acid as the solvent caused the best electrophoretic mobility and resulted in a less porous film compared to acetic acid and lactic acid.
