Abstract (en)

[origin: WO2020012102A1] The invention relates to a process for forming a polyarylene polymeric film on all or part of a metal substrate, characterized in that the film is formed spontaneously by simply bringing the part(s) of the substrate to be coated with the film into contact with a gel comprising at least one aryldiazonium salt and at least one gelling agent and characterized in that the metal substrate is a reducing metal substrate.
