Title:
CONDUCTIVE INK COMPOSITIONS COMPRISING GOLD AND METHODS FOR MAKING THE SAME
Document Type and Number:
Japanese Patent JP2022136229
Kind Code:
A
Abstract:
To provide conductive ink compositions comprising gold and methods for making the same.SOLUTION: A particle-free gold-complex based ink is described where a gold carboxylate is complexed with an amine. Upon heating the solution, the gold cation catalyzes the oxidative amidation of the amine with the carboxylate to form a short-chain or polymeric amide while simultaneously reducing the gold cation to metallic gold. This method is extremely versatile and allows preparation of both pure metallic gold films and polymer gold composites with unique properties. In one aspect, ink compositions for making a conductive gold structure are provided which comprise a gold salt and a complexing agent, and optionally further comprises a short-chain carboxylic acid or salt thereof, where the gold salt is a carboxylate or is capable of forming a carboxylate with the short-chain carboxylic acid or salt thereof.SELECTED DRAWING: None
