Process for producing silver nanowires and agent for controlling growth of silver nanowires
Provided is a process for silver nanowire production in which the major-axis length of the silver nanowires can be controlled in a wide range and an agent for controlling the growth of silver nanowires. A process for silver nanowire production which is characterized in that an agent for controlling the growth of silver nanowires which comprises a polymer obtained by polymerizing one or more polymerizable monomers comprising an N-substituted (meth)acrylamide is reacted with a silver compound in a polyol at 25-180° C. The agent for controlling the growth of silver nanowires is characterized by comprising a polymer which has units of an N-substituted (meth)acrylamide as a polymerizable monomer.
