Multifractal Properties of Copper Sulfide Film Formed in Self-Organizing Chemical System

The growth of fractal films of copper sulfide formed during the oxidation of ascorbic acid by aerial oxygen in the presence of a copper coordination compound and sodium sulfide has been studied. The process of growth of the film can be divided into three parts: 1) generation of CuS centers of growth; 2) growth of CuS according to the diffusion limitation of aggregation mechanism; and 3) in the final stage the structure of the film does not change. A method is developed to obtain films with uniform fractal dimensions, but different values of fractal divergence.
