In the liquid phase, we get high pureness and excellent property nano Cu with the hydrazine dydrate as the reducer and the PVP and OP 10 as the dispersant. After the nano Cu is sensitized and acted, the nano Cu Ag Bimetallic Powders are got through 5% PVP and OP 10 are went into the plating solution and they are chemic plating. It is stated by the experimentation result that the powders can substitute Ag as the padding of conduction coating or shield coating.展开更多
