Conductive elastic silver paste suitable for 3D printing elastic probe and preparation method and application thereof

The invention belongs to the technical field of 3D printing, and particularly relates to conductive elastic silver paste suitable for a 3D printing elastic probe and a preparation method and application of the conductive elastic silver paste. According to the invention, the conductive elastic silver paste is prepared by mixing the low-cost micron-sized silver particles and the high-molecular elastic matrix, so that high conductivity can be realized. According to the conductive elastic silver paste, the interfacial compatibility between the micron-sized silver particles and the macromolecular elastic matrix is good, the adhesion of the conductive elastic silver paste is effectively improved, the phenomena of stripping, falling and layering of the silver particles are avoided, and the 3D printing performance of the conductive elastic silver paste is further improved. The conductive elastic silver paste disclosed by the invention has excellent elastic shrinkage performance while ensuring high conductivity, and a
