【 摘 要 】

This paper reports a facile and environmental method of synthesizing highly dendrite silver microstructure and flower-like gold, copper microstructure. By reducing AgNO3 CuSO4⋅5H2O, HAuCl4H2O with L-ascorbic acid in an ethyl alcohol solution without any dispersing agent, their morphology was formed in a few minutes. A mechanistic study of the growth process revealed that the silver branches grew from a bulbous seed formed through aggregation, and that by changing the concentrations of the reagents, the degree of particle branching could be altered. As we all know, the copper, silver and gold are possess of outstanding conductivity, and the dendrite silver have more contact spots than silver nanowires. So we prepare the dendrite silver for substituting the silver nanowires in flexible conducting device applications.
