GARCIA RUEDA, F. C.; PENA BALLESTEROS, D. Y.  and  ESTUPINAN DURAN, H. A.. Morphological and electrochemical behavior of polycaprolactone-chitosan-collagen film fabricated by Dip Coating on Ti6Al4V. Rev. mex. ing. bioméd [online]. 2017, vol.38, n.1, pp.54-75. ISSN 2395-9126.  https://doi.org/10.17488/rmib.38.1.4.

This paper presents the characterization by the infrared technique, atomic force microscopy, scanning electron microscopy and contact angle of the polymer coatings of the binary mixture of polycaprolactone-chitosan and its modification after addition of collagen were deposited by the technique of Dip Coating on Ti6Al4V alloy; also by the technique of Electrochemical Impedance Spectroscopy were evaluated the Ti6Al4V alloy coated by polymer blends zero days immersion in Simulate Bode Fluid and of adsorptivity calcium to 21 days immersion. Thus, representative effects on the role of collagen to increase the surface roughness, higher values in the polarization resistance of Ti6Al4V, better behavior parameters free energy, atomic adsorption of calcium and the consolidation of a found new interface associated with the monolayer calcium simulated by equivalent circuits and observed by Scanning Electron Microscopy.

Keywords : Ti6Al4V; polycaprolactone; chitosan; collagen; calcium adsorption.
