Abstract

The invention discloses graphene/nano-silver light-sensitive conductive composite paste and a preparation method therefor. The composite paste comprises the following raw materials based on weight: graphene and spherical nano-silver, wherein the weight ratio of graphene to spherical nano-silver is 1 to 2.0-3.5; and the preparation process comprises the steps of drying graphene and then mixing the raw materials under yellow light to obtain the composite paste. Due to the reasonable formula of the graphene and nano-silver and the new technological method, the light-sensitive silver paste obtains the characteristics of clear image development, high resolution, extremely high conductivity, high coating film strength and the like; the paste is subjected to silk-screen printing, letterpress printing, surface drying, exposing and developing to obtain a pattern with the required high resolution (L/S is greater than 30/30[mu]m); and in addition, the composite paste has excellent printing performance, high storage stability, excellent conductivity, high resolution, and high adhesive force.
