An alternative approach was developed for surface treatment of as-received commercial AA 2024 T3 by using a pyrrole-based silane (SiPy). For film deposition, just one immersion step is enough, followed by curing. SiPy layer structure contains both polysiloxane bonds and pyrrole oligomers, with some degree of doping, giving a highly coherent layer. The superior film quality with respect to simple polysiloxane, is probably the main reason for the better corrosion performance obtained for SiPy on 2024.

“…We have shown in previous studies of conducting-polymer systems that the redox potentials of the monomers are not the only determinants of polymer composition. For example the solubility of oligomers and the reactivity of the radical cations are also critical factors 22,23 especially when polymerisation is performed under a diffusion-controlled regime. Often it is the case that even though the oxidation potentials of monomers are similar, electrocopolymerisation from a 1 : 1 binary mixture yields a polymer material that significantly favours one component or the other.…”

Here we have studied the electrocopolymerisation of binary mixtures of functionalised thiophenes in varying compositions and determined independently for each copolymer the spectroelectrochemical responses and the composition of the material using x-ray photoelectron 15 spectroscopy. We have observed strong correlations between the composition of the copolymer material and the composition of the binary solution from which the polymer was grown. In addition, we have shown that the spectroelectrochemical properties of the copolymers indicate the presence of random copolymer material where the λ Max values of the neutral, undoped, polymer scales with composition but also suggest that there may be small amounts of block copolymer or 20 phase-separated mixtures of the homopolymer components.
