Nanostructures of CuO: synthesis and properties

Synthesis and characterization of nanostructures of CuO have received increasing attention from researchers during recent years. This is due to their excellent properties such as super-hydrophobic, high-strength, and good conductivity. In addition, they have a large range of potential application in heterogeneous catalysis, enhanced thermal conductivity, and anode materials for lithium ion batteries (LIBs) etc.

The synthesis of CuO nanostructures is an important and critical step to develop novel materials and applications. In this respect, several approaches have been employed to prepare CuO nanostructures. The most popular techniques are the hydrothermal and the electrochemical routes. The former route has been found to be more effective in producing stable CuO nanoparticles and a highly crystalline morphology.

To study the stability of CuO nanoparticles prepared in liquid phase, several surfactants were utilized. They had different polar heads that were absorbed on to the surface of the nanoparticles and hydrophobic tails that provided steric repulsion. The stabilizers could be used in different concentrations and concentration levels to obtain a suitable stabilizing effect on the CuO nanoparticles.

Various pressures and frequencies were measured to determine the dielectric constant and loss of the sample. The results show that the value of dielectric constant increases with frequency at low pressures and decreases at higher pressures.
