Here, we report for the first time on the successful fabrication of monodispersed silver nanocubes with regular shape and controlled size in the solid phase via a novel ion-exchange self-assembly technique by using water-soluble poly(amic acid) salt as the intermediate and silver nitrate as the metal precursor. By simply altering the annealing times at high temperature, the size of the silver nanocubes could be finely tuned in the range of 90-160 nm in the present case. Further attempts with different metal salts show that the present method is also feasible for other metal species and might be universal.
在这里，我们首次报道了一种通过新颖的离子交换自组装技术，在固态下成功制备具有规则形状和受控尺寸的单分散银纳米立方体的方法。该方法以水溶性聚酰胺酸盐作为中间体，以硝酸银作为金属前体。通过简单改变高温下的退火时间，在本研究中可以将银纳米立方体的尺寸在 90-160nm 的范围内精细调节。进一步尝试使用不同的金属盐表明，该方法对于其他金属物种也是可行的，可能具有普遍性。
