TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The composition further comprises metal nano particles (0.5-5 wt.%), at least one additive (0.1-10 wt.%), a solvent, and a binder. Preferred Components: The silver nano particles have an average particle size of 1-100 (preferably 5-40) nm. The metal nano particles are at least one selected from copper, tin, gold, platinum and palladium. The metal microplates are made of at least one selected from silver, copper, tin, gold, platinum, palladium and aluminum. The micrometer-sized plane perpendicular to the thickness direction has horizontal and vertical sides of 1-20 mu m size on average. The additive is selected from stabilizer, dispersant, reducing agent, surfactant, wetting agent, thixotropic agent, leveling agent, antifoaming agent, coupling agent, surface tension adjusting agent and thickener. The metal-coated carbon nanotubes are carbon nanotubes with a metal which is at least one selected from silver, tin, platinum, gold, palladium and/or ion complexes.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The solvent is selected from ketone, alpha-terpineol, glycol and alcohol. The binder is selected from acryl, vinyl, nitrocellulose, ethyl cellulose and/or modified resins. The conductive ink has a specific resistance of 2x 10-6 to 10x 10-6 Omega cm; and has a sintering temperature of 110-150 degrees C. EXAMPLE - A component-A comprising spherical silver nanoparticles (70 wt.%) having average particle size of 5-20 nm, in tetradecane dispersant solution (20 g) was prepared. A component-B comprising silver microplates (50 g) dispersed in butyl carbitol acetate solution (20 g) was prepared. A component-C comprising acryl resin (10 g) dissolved in terpinol solution as a binder (30 wt.%) was prepared. The components A, B and C were preliminarily mixed and agitated using a 3-roll mill till the components are uniformly dispersed. Next, a resultant paste was uniformly printed on a PET substrate at a size of 6x 6 cm by screen printing to form a uniform film. The substrate was sintered at 130 degrees C for 2 minutes in a convection oven to manufacture a paste containing silver nanoparticles and silver microplates.
