Abstract
A non-catalytic method for making high aspect ratio metal particles comprises: mixing a preheated metallic salt solution with a preheated reducing solution, the reducing solution comprising a carboxylic acid or salt thereof and an acrylic copolymer; and heating the reaction mixture to a first temperature and maintaining the mixture at the first temperature for a first period of time, then heating the reaction mixture to a second temperature that is higher than the first temperature and maintaining the mixture at the second temperature for a second period of time. The metal cations in the metallic salt are reduced by the reducing solution to form a plurality of crystallized metallic particles having a high aspect ratio. Electrically conductive articles incorporating the high aspect ratio metal particles and methods for their manufacture are also provided.
