This work presents a new method to prepare poly(sodium acrylate) magnetite composite nanoparticles. Core/shell type magnetite nanocomposites were synthesized using sodium acrylate as monomer and N,N-methylenebisacrylamide (MBA) as crosslinker. Microemulsion polymerization was used for constructing core/shell structures with magnetite nanoparticles as core and poly(sodium acrylate) as shell. Fou...

Cashew nut testa tannin [CASTAN] has been found to inhibit the corrosion of aluminium in hydrochloric acid solutions using gravimetric, thermometric and UV/visible spectrophotometric techniques. CASTAN inhibition was by adsorption on aluminium following Temkin isotherm in 0.1 M HCl and Langmuir isotherm in 0.5 M and 2.0 M HCl at 303 Kelvin. Physical adsorption on aluminium has been proposed in ...

The efficiency of Schiff base derived from 4-aminoantipyrine, namely 2-(1,5-dimethyl-4-(2-methylbenzylidene)amino)-2-phenyl-1H-pyrazol-3(2H)-ylidene) hydrazinecarbothioamide as a corrosion inhibitor on mild steel in 1.0 M H2SO4 was investigated using electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PD) and electrochemical frequently modulation (EFM) in addition to the...

This work deals with the evaluation of diphenyl sulphide as a corrosion inhibitor for zinc in 0.5N HCl and 0.5N H2SO4 by conventional weight loss and gasometric methods. Results indicate that diphenyl sulphide exhibited high inhibition efficiencies in both the acids but performed better in 0.5N H2SO4 than in 0.5N HCl. The inhibition efficiency was found to increase with increase in the inhibito...

Schiff base ligand, 2-acetylpyridine 4-methyl-3-thiosemicarbazone (Me-LH), and its organotin complex (BuSn(Me-LH)Cl2) were synthesized, characterized, subjected to corrosion inhibition study. The spectra crystal structure obtained revealed that the ligand is coordinated by pyridyl nitrogen, azomethine thiolate sulfur (IV) ion. Corrosion of synthesized compounds on mild steels in 1 M HCl solutio...

Polymer-based coatings are a long-established category of protective for metals and alloys regarding corrosion inhibition. The polymer films can degrade, when coated on metallic substrates, the degradation facilitates moisture oxygen penetration, reducing film’s adhesion to substrate exposing extreme conditions capable corrosion. For this reason, pigments, inhibitors, other compatible blends ad...
