Scientific Interests

Domain of specialization

Conducting polymers;Non linear optics;

Electrochemical techniques: cyclic voltammetry, electrochemical impedance spectroscopy, crystal impedance/EQCM; Structural and compositional techniques techniques: X-ray absorption spectroscopy (XAS: XANES and EXAFS); X-ray photoelectron spectroscopy (XPS); Electron (FE-SEM) and atomic force (AFM) microscopies;

Current interests

Nano and microencapsulation applied to corrosion science

Development of nanocontainers for controlled release of active substances and their incorporation into coating matrices, and electrochemical characterization

‘Smart’ corrosion protection based on ‘self-healing’ effect, nanostructured protective coatings, mechanisms of corrosion inhibition. Development of anticorrosion coatings for aeronautical, automotive and maritime industries. Development of nanocontainers for controlled release of active substances (corrosion inhibitors, biocides, sensing species).


Present Research Group

SECOP-Surface Engineering and Corrosion Protection Group

Prof. Mario Ferreira is leader of the Surface Engineering and Corrosion Protection group. SECOP holds an extensive experience in the field of anti-corrosion coatings for metal alloys. The group is currently working on complementary areas, including the development of micro and nanorecipients for encapsulation of corrosion inhibitors, to provide a controlled and prolonged release of the inhibiting species for self-healing coatings and the investigation of corrosion inhibition and self-repairing processes at micro-/nano-level by localized electrochemical techniques.
