Preparation of functionally graduated materials by electrophoretic deposition
Keywords:Electrophoretic deposit, Corrosion, Functionally graduated material, Hydrophobic surface, PDMS.
The objective of this work is to develop a superhydrophobic and self-healing coating with the ability to protect metal surfaces and extend the useful life of both metal and coating. By means of the electrophoretic deposition technique, titanium dioxide coatings with variable morphology and composition were created. So far two techniques have been used for the manufacture of superhydrophobic coatings: 1) Functionalization of TiO2 nanoparticles (anatase) with polydimethylsiloxane by UV irradiation and 2) Functionalization of electrophoretic deposits with polydimethylsiloxane by UV irradiation. The electrophoretic deposits vary the applied potential and the deposition times, they are observed that they are used, they are eliminated, the uniforms are uniform and homogeneous, they are minimized, they are reduced, they are diminished, they are diminished, they are diminished, they are increased, they are they increase, they increase, they increase, they decrease, they increase, they are deposited first, thus generating a homogeneous arrangement on the surface of the highly rough metal. All deposits were characterized by FTIR, RAMAN, DLS, UV-vis- Diffuse Reflectance, AFM y FESEM.
