Abstract
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.
Claims18
A method of producing silver nanofilaments, the method comprising 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 mixture to react;
- and
- recovering silver nanofilaments, wherein the method is carried out at temperatures ranging from about 15° C. to about 25° C.
A method of producing silver nanofilaments comprising the steps of:
- adding solid silver salt selected from the group consisting of silver nitrate and silver acetate to a liquid ether selected from the group consisting of diethyl ether, di-tert-butyl ether, diglycol methyl ether, diisopropyl ether, dimethoxyethane, dimethoxymethane, dioxane, ethyl tert-butyl ether, methoxyethane, methyl tert-butyl ether, 2-methyltetrahydrofuran, tetrahydrofuran, dioxane, and tetrahydropyran and combinations thereof to form a mixture;
- adding a long-chain fatty acid selected from the group consisting of myristoleic acid, palmitoleic acid, sapienic acid, oleic acid, linoleic acid, and alpha-linoleic acid and combinations thereof to the mixture;
- adding a diamine reducing agent to the mixture;
- allowing the mixture to react for between about 15 minutes and about 180 minutes;
- and
- recovering silver nanofilaments, wherein the method is carried out at temperatures ranging from about 15° C. to about 25° C.
