“…These findings can be interpreted as follows: FCC metals, such as Ag, exhibit a preferential (111) orientation since the (111) plane is associated with the lowest surface energy and the highest atom packing density [ 38 ]. This trend holds for polycrystalline Ag thin films, in which the crystallographic texture depends on multiple parameters: deposition conditions, the nature of the substrate, film thickness, or post-deposition annealing [ 39 , 40 , 41 ]. The latter generally leads to an increase in texture on the (111) plane for thin silver films [ 41 ].…”

The latter generally leads to an increase in texture on the (111) plane for thin silver films [ 41 ]. Indeed, thermal post-annealing and the ensuing spatial reorganizations minimize the total energy of these systems, i.e., the balance between the surface energy and the elastic deformation energy components.…”

In this work, the effect of thermal annealing on silver nanoparticles@polymer (AgNPs@polymer) nanocomposite coatings was investigated. These photo-generated metallized coatings have a spatial distribution of metal nanoparticles, with a depth-wise decrease in their concentration. During annealing, both structural and morphological variations, as well as a spatial reorganization of AgNPs, were observed, both at the surface and in the core of the AgNPs@polymer coating. Owing to their increased mobility, the polymer chains reorganize spontaneously, and, at the same time, a hopping diffusion process, caused by the minimization of the surface energy, promotes the migration and coalescence of the silver nanoparticles towards the surface. The layer of discrete nanoparticles gradually transforms from a weakly percolative assembly to a denser and more networked structure. Consequently, the surface of the coatings becomes significantly more electrically conductive, hydrophobic, and reflective. The general trend is that the thinner the nanohybrid coating, the more pronounced the effect of thermal annealing on its spatial reorganization and properties. These results open up interesting prospects in the field of metallized coating technology and pave the way for integration into a wide variety of devices, e.g., efficient and inexpensive reflectors for energy-saving applications, electrically conductive microdevices, and printed electronic microcircuits.
