英文摘要 | To research the effect of surface dispersants on nano-copper powders, taking sodium dodecyl sulfate, Tween20, Tween40, Tween80 and their composites as surface dispersants, some nano-copper powders with different particle shape and size were prepared by electrochemical method. The phases of nano-copper powders were analyzed by XRD and FT-IR, and the morphology and particle size were analyzed by TEM. The results show that different surface dispersants play different role in the preparing process of the nano-copper powders. The sodium dodecyl sulfate can prevent the powder from oxidation due to electrostatic attraction of double electricity layer and steric barrier effect. Tweens can control the powders aggregation accompanied with higher steric barrier effect, of which the Tween -80 has the best effect. However, the resulting nano-copper powders can be oxidized and aggregated during electrochemical processing with single surface dispersant. When the sodium dodecyl sulfate and Tween80 are used together, the resulting nano-copper with particle size of 20~50 nm can be obtained by electrochemical method, because stronger electrostatic attraction of double electricity layer of sodium dodecyl sulfate and higher steric barrier effect can prevent the powders from oxidation and aggregation. |
