EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

This presentation will summarise our recent works on the synthesis of functional nanocomposites thin films based on metal atom clusters by a chemical solution deposition (CSD) process namely electrophoretic deposition (EPD) [1-10]. CSD processing of inorganic nanocolloidal solutions is generally acknowledged to be highly flexible in terms of precursor composition, targeted substrate and procedures (dip-spin coating, spray coating, EPD…) in ambient pressures, and thus can be faster and less expensive than physical-based deposition routes while providing materials with matching or even superior properties. In this study, several octahedral atom clusters were characterised and used to prepare highly transparent thin films in the visible. Various coloured and transparent films were successfully fabricated on ITO glass substrates. In addition, transparent films with prominent photoactive or antibacterial properties were obtained by using specific Mo6 clusters whereas UV and NIR filters were realised by using Ta6 and Nb6 clusters. The EPD process appears a performant CSD strategy to fabricate highly transparent and coloured nanocomposite thin films for optical, biological and energy applications.
