摘要：

The nucleation and growth of nascent Cu(0) nanoparticles formed by disproportionation during SET-LRP on the surface of Cu(0) wire was demonstrated by Scanning Electron Microscopy analysis of the surface of Cu(0) wire before and after disproportionation and polymerization. The dynamics of nascent Cu(0) formation, activation of dormant species and their nucleation and growth on the existing Cu(0) surface determines the Cu(0) consumption during polymerization.
