Ionic liquids as two-dimensional templates for the spontaneous assembly of copper nanoparticles into nanobelts and observation of an intermediate state

摘要

An intermediate state was observed during the self-assembly of copper nanoparticles into nanobelts in a solution of ionic liquids. The copper nanoparticles produced in a solution of ionic liquids and ethanol were observed to spontaneously aggregate and firstly formed discrete copper belt-shaped structures before gradually merging into continuous copper nanobelts.
