Effect of Sonification Time on Synthesisi and Corrosion Resistance of Epoxy-Clay Nanocomposite

In recent years many research works have been carried out on anti-corrosive nanocomposites coatings containing mineral reinforcements. The most important criteria in these attempts are polymerization method and the type of matrix and reinforcement of nanocomposites. In this regard, the physical and...

The most important criteria in these attempts are polymerization method and the type of matrix and reinforcement of nanocomposites. In this regard, the physical and mechanical properties of the polymers in which a small amount of filler is used can be improved. In this research, an epoxy-clay nanocomposite was synthesized by in-situ polymerization method using a resin matrix based on bisphenol-A type epoxy and montmorillonite clay (Closite 15A). The treatment was used at different ultrasonic stirring times to disperse 1-4 weight percentages of clay particles into the matrix. The structure of synthesized epoxy-clay nanocomposite was studied by scanning electron microscopy and X-ray diffraction techniques. The average size of clay particles was determined by X-ray diffraction measurement. Then, anti-corrosion properties of epoxy-clay coatings, prepared under different ultrasonic durations and applied on carbon steel panels, were investigated by Tafel and electrochemical impedance spectroscopy techniques. For this purpose, the carbon steel panels coated with these coatings were immersed in 3.5% sodium chloride solution and tested at different immersion times. The results indicated that a nanocomposite containing 1% clay, synthesized, stirred 60 min ultrasonically, produced smaller particle size, lower corrosion current density and higher coating corrosion resistance than the other composite formulations. This nanocomposite provided superior protection against corrosion in sodium chloride solution.

abstract	In recent years many research works have been carried out on anti-corrosive nanocomposites coatings containing mineral reinforcements. The most important criteria in these attempts are polymerization method and the type of matrix and reinforcement of nanocomposites. In this regard, the physical and mechanical properties of the polymers in which a small amount of filler is used can be improved. In this research, an epoxy-clay nanocomposite was synthesized by in-situ polymerization method using a resin matrix based on bisphenol-A type epoxy and montmorillonite clay (Closite 15A). The treatment was used at different ultrasonic stirring times to disperse 1-4 weight percentages of clay particles into the matrix. The structure of synthesized epoxy-clay nanocomposite was studied by scanning electron microscopy and X-ray diffraction techniques. The average size of clay particles was determined by X-ray diffraction measurement. Then, anti-corrosion properties of epoxy-clay coatings, prepared under different ultrasonic durations and applied on carbon steel panels, were investigated by Tafel and electrochemical impedance spectroscopy techniques. For this purpose, the carbon steel panels coated with these coatings were immersed in 3.5% sodium chloride solution and tested at different immersion times. The results indicated that a nanocomposite containing 1% clay, synthesized, stirred 60 min ultrasonically, produced smaller particle size, lower corrosion current density and higher coating corrosion resistance than the other composite formulations. This nanocomposite provided superior protection against corrosion in sodium chloride solution.

The most important criteria in these attempts are polymerization method and the type of matrix and reinforcement of nanocomposites. In this regard, the physical and mechanical properties of the polymers in which a small amount of filler is used can be improved. In this research, an epoxy-clay nanocomposite was synthesized by in-situ polymerization method using a resin matrix based on bisphenol-A type epoxy and montmorillonite clay (Closite 15A). The treatment was used at different ultrasonic stirring times to disperse 1-4 weight percentages of clay particles into the matrix. The structure of synthesized epoxy-clay nanocomposite was studied by scanning electron microscopy and X-ray diffraction techniques. The average size of clay particles was determined by X-ray diffraction measurement. Then, anti-corrosion properties of epoxy-clay coatings, prepared under different ultrasonic durations and applied on carbon steel panels, were investigated by Tafel and electrochemical impedance spectroscopy techniques. For this purpose, the carbon steel panels coated with these coatings were immersed in 3.5% sodium chloride solution and tested at different immersion times. The results indicated that a nanocomposite containing 1% clay, synthesized, stirred 60 min ultrasonically, produced smaller particle size, lower corrosion current density and higher coating corrosion resistance than the other composite formulations. This nanocomposite provided superior protection against corrosion in sodium chloride solution.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield
