Abstract
Methods of preparing metal nanowire are disclosed that employ quaternary phosphonium salts. Such processes can produce long and thin nanowires. Compositions and articles comprising such nanowires are useful in electronics applications.
Claims9
A method comprising:
- providing at least one first compound capable of forming at least one first halide ion, said first compound comprising at least one quaternary phosphonium salt represented by (I):
- wherein R1, R2, R3, and R4 each independently comprise an alkyl group, an aryl group, an alkoxy group, or an aryloxy group, and X− comprises a halide ion;
- and
- reducing at least one first reducible metal ion to at least one first metal nanowire in the presence of at least one of the at least one first compound or the at least one first halide ion.
