Effect of polymerised ionic liquid based gel inhibitor on SNAP coating
In a new study the inhibition performance of polymerised ionic liquid (PIL) based gel inhibitors was evaluated in SNAP coating.
The corrosion process is a surface reaction that can be controlled by the addition of corrosion inhibitors, which adsorb on the reacting metal surface. The inhibitors could be applied to a metal surface in many different ways. In a new contribution, influence of polymerised ionic liquid (PIL) was examined on inhibition performance of a coating using carbon steel samples.
Strong interfacial properties
The PIL was loaded in self-assembled nanophase particle (SNAP) coating and the inhibition behaviour was investigated using potentiodynamic polarisation, electrochemical impedance spectroscopy and scanning kelvin probe techniques. The inhibition efficiency of the coating increases with the addition of PIL as observed from potentiodynamic polarisation and electrochemical impedance spectroscopy (EIS) measurements. In addition, scanning kelvin probe (SKP) measurement provides further understanding on the strong interfacial properties of the modified coating compared to that of the SNAP.
