A method of producing silver nanofilaments that is relatively fast and may be carried out at normal room temperatures (e.g., from about 10° C. to about 25° C.). The method of producing silver nanofilaments includes the steps of adding a solid silver salt to liquid ether to form a mixture, adding a liquid fatty acid to the mixture, adding a reducing agent to the mixture, allowing the ingredients to react, and recovering silver nanofilaments.
