“…Regarding nanocomposite thin films based on metallic fillers in polymer matrices, most of the synthesis approaches are based on the insertion of pre-synthesized nanostructures, for which numerous method exist 23,24 , into polymer solutions 25,26 . In this case, it is challenging to prevent the formation of nanoparticle aggregates and, for this reason, the use of stabilizing agents is required to obtain homogeneously dispersed nanoparticles 27 . Moreover, it is difficult to maintain a homogeneous spatial distribution at large scales using standard procedures such as coating or evaporation.…”
