摘要:In this paper, copper dendrites decorated with ZnO rods have been electrolessly deposited on brass substrate by a simple galvanic replacement method. SEM images show that these copper dendrites possess a pronounced trunk and highly ordered branches distributed on both sides of the trunk. Meanwhile, both the trunk and branches are decorated with ZnO rods. The diffusion-limited aggregation (DLA) model has been used to explain the fractal growth of Cu dendritic structures, This method provides a facile route to the synthesis of copper dendrites with ZnO, which can be extended to the preparation of other forms three-dimensional (3-D) metal structures or metal/ZnO composites by modifying electrolyte parameters such as composition, concentration, pH and temperature.
