Carbon nanotubes and graphene for flexible electronics

This paper explores the preparation method of copper/silver alloy nanoparticles. Firstly, using the environmental friendly ascorbic acid as reducing agent, the small particle size of nano-copper is prepared. But nano copper has poor stability, and easily oxidized. In order to improve its stability, we add a small amount of Ag＋ to prepare nano copper. The silver layer covers nano copper surface by reduction reaction. The copper/silver alloy nanocrystalline have good stability, and the alloy have also nanoparticles effect. The copper/silver alloy nanoparticles expect to be applied potentially in production of printed electronics.
