Optimization of Chitosan-Based Scaffolds Obtained via Cathodic Polarization

Abstract:

Cathodic polarization is a powerful technique largely used for the deposition of thin films on metallic substrates; it offers the distinctive advantage of an easy control over the composition, thickness, and morphology of the films by simply adjusting the process parameters such as the electrolyte bath composition, the applied potential (or current density), and the process duration. In this work, electrochemical deposition (ECD) was exploited to engender biopolymer blends composed by chitosan/collagen and chitosan/poly (ethylene oxide) and deposited at different weight ratios (5:1, 3:1) and compared to pristine material. Our findings demonstrate that ECD is an effective technique for the preparation of scaffolds made of chitosan blends in which morphology and mechanical properties can be optimized via scaffold composition.
