Supported Cu0 nanoparticles catalyst for controlled radical polymerization reaction and block-copolymer synthesis
Abstract The synthesis of Cu0 nanoparticles on different supports and their activity in controlled living radical polymerization processes is presented. The type of support influences the final size of the copper nanoparticles as well as their adhesion to the support. These aspects have a direct inf...
