Definitions

  • this synthesis is not a selective reaction, and impurities are produced during the synthesis, in particular small nanoparticles, aggregates (agglomerated nanoparticles) and large particles, for example of the stick type.
  • impurities are produced during the synthesis, in particular small nanoparticles, aggregates (agglomerated nanoparticles) and large particles, for example of the stick type.
  • these co-products can have a negative impact on the performance of the electrodes (lower transmittance with identical conductivity, high roughness, etc.).
  • the large particles may more particularly have at least two dimensions of between 250 and 5000 nm.
  • the solvent medium S2 is preferably added in a volume such that the suspension thus formed has a concentration of metal material forming the metal nanofilaments, for example silver in the case of silver nanowires, between 0.1 and 10 g / L, in particular between 0.1 and 4 g / l.
  • the solvent medium S2 is devoid of ketone. In particular, it does not include acetone.
  • nanowires of the initial mixture can be removed during the different steps of the process of the invention, especially when the main objective is to obtain a final solution of nanowires, totally devoid of inorganic particles annexes.
  • the nanowires may be subjected to an acid treatment, via (a) contacting the metal nanowires (dispersed in the supernatant or redispersed in a solvent such as water or methanol) with a solution of an acid, this solution having a pH of less than 7, preferably less than 3, followed by (b) the removal of the acid.
  • the suspension is then distributed in three crystallizers (6.5 cm diameter), and set to decant.
