PREPARATION METHOD FOR ELECTRICAL CONDUCTIVE SILVER NANOPARTICLE INK AND SILVER NANOPARTICLE FILM

摘要

Invention is the low molecular weight PVP (polyvinylpyrrolidone) for the silver inks for being used to prepare the TiO silver inks produced like that, and 2 are related to a kind of preparation method, is used for a silverskin, and the electric conductivity of film is improved by increasing a. According to the present invention, the number-average molecular weight in distilled water is no more than 50,000 PVP (polyvinylpyrrolidone), is a precursor, stirs into a reducing agent followed by further to produce one first solution; The first solution is centrifuged to a centrifugal separator to prepare one second solution, containing precipitating and keeps solvent, in chimjeom separation waterborne; Separate the residual solvent of the second solution and final sediment; A method of it is excellent in terms of dispersate for manufacturing conductive silver inks comprising to may be added to the method provided for producing a silverskin for a solvent of precipitating and the nano-ink TiO 2 of silvery.
