Abstract
This paper presents the production of an epoxy paint associated with a determined concentration of PAni emeraldine base binder, in order to increase dispersion of PAni polymer chains in the paint allow physical contact between PAni chains, the electrolytic medium, and the metal of interest. The coating called Intelligent Epoxy Paint (IEP) seeks to potentialize the electrolytic capacity of PAni to produce passivation, differentiated research which uses PAni in oxidized and conductive form as paint pigment that needs high PAni concentrations. The physicochemical characterization and morphological presented results that indicate the preservation of the desirable properties of PAni in order to make the passivation process possible. The electrochemical tests showed the passivation and/or maintenance of the passivation of the metal of interest, without the need to apply an external current.
Highlights
The use of organic coatings has been presented as an alternative for corrosion protection of metallic materials in harsh environments
commercial paint (CEP) samples applied using a 200 μm spacer had an average thickness of 178.43 μm with a CEP samples applied using a 200 μ m spacer had an average thickness of 178.43 μ m with a standard deviation of 34.67 μm
According to the proposed objectives, from the production of PAni EP and its passage through the doping process to the PAni EB, it was possible to produce a PAni EB binder using the solvent CH2 Cl2 and the plasticizer CMP, which has no properties that may interfere with the desired characteristics of the PAni, according to the physicochemical results presented
Summary
The use of organic coatings has been presented as an alternative for corrosion protection of metallic materials in harsh environments. The industrial production of organic coatings with anticorrosive capacity is consolidated with the use of inorganic inhibitors. These components (Zr, Cr, Pb, Zn and others) have as an inconvenience the possible environmental contamination and human health due to their toxic and/or carcinogenic nature [1,2,3]. ICP polyaniline (PAni) has aroused significant interest in the scientific and technological environment for years due to the low cost characteristics of the monomer (aniline), the ease of synthesis, the excellent stability under certain environmental conditions in both non-conductive and conductive form, the ability to become electronic and ionic insulator in the oxidized state, representing desirable properties for the production of barrier effect in coatings and enabling the oxidation reactions capable of forming and/or preserving passivating oxides for various passivable metals, in addition to possessing properties that make it possible to obtain free-standing films [1,4,5]
