Copper is different from metals such as aluminum and nickel in that it is difficult to form a dense and stable intrinsic passivation layer on its surface. Therefore, the exposed copper surface will be continuously oxidized and corroded by oxygen and water vapor in the air. The smaller the particle size and larger the specific surface area of copper powder, the easier it is to rapidly oxidize to produce products such as cuprous oxide (Cu2O) and copper oxide (CuO). This oxide insulation layer significantly reduces the conductivity of copper powder and hinders particle sintering connection, resulting in degradation of the performance of the conductive paste.

Researchers have made a breakthrough in the development of carbon nanotube (CNT) reinforced aluminum composites by utilizing ultra-short CNTs with unique intra-crystalline dispersibility. The nanoscale carbon nanotubes are uniformly distributed within the ultra-fine aluminum grains. When compared with typical CNT/Al composites with inter-granular CNT dispersion, this intra-crystalline carbon nanotube/aluminum composite has a stronger ability to anchor and maintain dislocations, resulting in enhanced strength and ductility. This innovative intra-crystalline dispersal strategy provides a new avenue for developing strong and tough nanocarbon reinforced metal-based composite materials. The research has been published recently in a prestigious academic journal.
