Shape Control of Silver Tree by Pulse Electro-deposition Method in AgNO₃ Aqueous Solution

抄録

Dendrite silver was synthesized on the carbon fiber by pulse electro-deposition method in AgNO₃ aqueous solution. The morphology of the silver changed from dendrite to plate like crystal, and the formation mechanism was investigated by using continuous wave (CW) potential and rectangular wave potential. The fractal dimension of the silver tree deposited at 10 Hz showed the highest value in the each low of the potential, V_L, of rectangular wave. The shape of the silver tree is able to control by adjusting the frequency of the rectangular wave that applied for electro-deposition.
