▎ 摘  要

NOVELTY - A screen printing silver nanowire/graphene conductive ink comprises 0.1-5 pts. wt. silver nanowire, 0.0025-1.5 pts. wt. graphene, 2.94-150 pts. wt. ethanol, 3.56-178 pts. wt. water, 0.52-26 pts. wt. ethylene glycol and 1-5 pts. wt. hydroxypropyl methylcellulose. The weight ratio of silver nanowire and graphene is 1: 0.025-1: 1.25. The silver nanowires are synthesized by using polyol method using polyvinylpyrrolidone as growth control agent and protective agent. USE - Screen printing silver nanowire/graphene conductive ink. ADVANTAGE - The method is simple. The conductive ink has low graphene content and good conductive performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparation of screen printing silver nanowire/graphene conductive ink comprising adding water into ethanol dispersion of silver nanowire, uniformly stirring, adding pasty viscous solid, uniformly stirring, adding graphene, and uniformly stirring to form a screen printing silver nanowire/graphene conductive ink, where the pasty viscous solid is prepared by adding hydroxypropyl methyl cellulose into water stirring, forming paste-shaped solid, adding ethylene glycol into paste-shaped solid while stirring, and forming stable and uniform system; and (2) application method of screen printing silver nanowire/graphene conductive ink comprising printing conductive ink on fabric substrate by screen printing method, baking at 130-180degrees Celsius for 2-30 minutes, and forming a conductive circuit with resistance of 0.29-0.54 kOmega.
