Impedance studies of poly(methylmethacrylate-co-acrylic acid) doped polyaniline films on aluminum alloy

Adhesion of Polyaniline on Metallic Surfaces

“…According to different authors (Dominis et al, 2003;Cook et al, 2004), at least three different configurations of PAni used as a corrosion protector have been reported: coatings alone, such as solution cast PAni films formed or electrochemically synthesized (Santos et al, 1998;Huerta-Vilca et al, 2003b, 2004aFahlman et al, 1997), coatings as primer with a conventional polymer topcoat (Dominis et al, 2003;Talo et al, 1997), and PAni blended with a conventional polymer coating or polymer coatings containing PAni as an additive (Galkowski et al, 2005;Samui et al, 2003;Sathiyanarayanan et al, 2009). Kinlen et al (Kinlen et al, 1997) and other authors Oliveira et al, 2009) observed that the electrochemically produced conducting polymers, as PAni, shift the corrosion potential (E corr ) of the metal to the passive region, maintaining a protective oxide layer on the metal and minimizing the rate of metal dissolution (Eq. 1).…”

“…3), stabilizing polymer coatings from cathodic disbondment. According to the above reaction sequences, the conducting polymer catalyses the oxide layer growth, protecting the metallic surface against corrosion (Oliveira et al, 2009).…”

Thermoelectrical characterization of new material based on PANI/zeolite HY composite, used for the detection of carbon dioxide

“…5 The use of PANI alone is hampered by poor mechanical properties; therefore, several studies have focused on eliminating such problems by mixing PANI with various polymeric matrices (PVA, PMMA, PSS, and so on). [6][7][8][9][10][11] Recently, PANI has also been dispersed in inorganic matrices. PANI/inorganic material composites have attracted great interest because of their resulting chemical, electrical and mechanical properties.…”

Electrochemical oxidation of aniline on the surface of an amorphous metal alloy Al87Ni8Y5

“…Aluminum and its alloys are suitable materials for the electrochemical deposition of different electroactive films and layers including PANI [10][11][12][13]. Electroactive polymers and, particu larly, PANI were actively studied recently as the possi ble ingredients of composition materials or as the basic substance used in the corrosion protection of Al and its alloys [14][15][16][17][18]. However, the mechanism of the direct formation of PANI films and layers on Al or Al con taining materials under potentiodynamic conditions from aqueous solutions is still unclear.…”
