Nanowire preparation methods, compositions, and articles
View Patent ↗Nanomaterial preparation methods, compositions, and articles are disclosed and claimed. Such methods can provide nanomaterials with improved morphologies relative to previous methods. Such materials are useful in electronic applications.
1. A method comprising:
providing at least one first composition comprising at least one silver ion;
providing at least one compound comprising thorium (IV) nitrate tetrahydrate; and
reducing the at least one silver ion to at least one silver metal nanowire in the presence of a solution comprising at least one thorium ion,
wherein the at least one silver metal nanowire consists of elemental silver.
2. The method according to claim 1 , wherein the reduction occurs in the presence of at least one protecting agent or at least one polyol.
3. The method according to claim 1 , wherein the at least one silver metal nanowire comprises an average diameter between about 10 nm and about 500 nm.
4. The method according to claim 3 , wherein the at least one silver metal nanowire comprises an average diameter less than about 40 nm.
5. The method according to claim 1 , wherein the at least one silver metal comprises an aspect ratio between about 50 and about 10,000.
