Preparation method of nano-silver-based flexible electronic circuit

The invention discloses a preparation method of a nano-silver-based flexible electronic circuit, which belongs to the field of flexible printed electronic circuits, and is characterized by comprising the following steps: (1) preparing nano-silver particles; (2) preparing a nano-silver-based flexible electronic circuit: dispersing the prepared nano-silver particles in an alcohol cosolvent, and performing ultrasonic oscillation to obtain nano-silver sol; the method comprises the following steps: uniformly mixing nano-silver sol with an adhesive emulsion, slowly stirring at room temperature to obtain a conductive adhesive, uniformly printing a printed pattern on the surface of a flexible substrate by using the conductive adhesive through silk-screen printing, and curing the printed pattern to obtain the nano-silver-based flexible electronic circuit. The solvent evaporation and forming process is completed by adopting a one-step method, the problem that a metal flexible base material often needs secondary high-te
