Preparation of stable colloids of copper nanoparticles in organic solvent with amphiphilic polymer

Key Words:amphiphilic polymer; copper colloid

Abstract:A method of preparing stable colloid copper nanoparticle by reduction of CuCl was introduced. PEO-PPO-PEO and Cyanex 302 were employed to prepare high concentrated copper colloid. The copper colloidal dispersion was analyzed by UV-vis and TEM techniques. The results show that the stability of copper colloid is mainly due to steric forces.
