Special Issue Information

Nanostructured materials in the form of thin films and nanocoatings are of high scientific and industrial interest. In the last four decades, they have experienced continuous intense development because of the high demand for improved performance and advanced new functionalities required for their incorporation into technological devices as a general need common to most industrial developments.

Identification of the key microstructural features and/or the singular electronic configurations in these new nanomaterials and understanding how they are linked to their final performance is of utmost importance.

Today, nanostructured films and nanocoatings are integrated into technological devices such as solar cells, fuel cells, batteries, smart windows, electrolyzers, electrochemical or optical transducers, photocatalytic platforms, etc., which provides them singular or enhanced performances and represents a highly valuable improvement geared towards advanced applications.

In this Special Issue, we invite the scientific community working in this exciting field to publish recent research and/or review papers contributing to progress in the understanding of links between the improved properties of nanostructured thin films and nanocoatings and their advanced performance in particular applications.

In this work, the electrografting of Al-7075 aluminium alloy substrates with 4-nitrobenzenediazonium salt (4-NBD) films was studied on a complex aluminium alloy surface. Prior to the electrografting reaction, the substrates were submitted to different surface treatments to modify the native aluminium oxide layer and unveil intermetallic particles (IMPs). The formation of the 4-NBD films could be correlated with the passive film state and the distribution of IMPs. The corresponding electrografting reaction was performed by cyclic voltammetry which allowed the simultaneous analysis of the redox reaction by a number of complementary surface-analytical techniques. Spatially resolved thin film analysis was performed by means of SEM-EDX, AFM, PM-IRRAS, Raman spectroscopy, XPS, and SKPFM. The collected data show that the 4-NBD film is preferentially formed either on the Al oxide layer or the IMP surface depending on the applied potential range. Potentials between −0.1 and −1.0 VAg/AgCl mostly generated nitrophenylene films on the oxide covered aluminium, while grafting between −0.1 and −0.4 VAg/AgCl favours the growth of these films on IMPs.
