Sažetak
Recent work on understanding colloidal aggregation phenomena using fractal geometry is reviewed. After describing a typical aggregation experiment, the concepts of fractal and fractal dimension are introduced and some simple models fit to describe the mechanism of diffusion-limited aggregation leading to fractal aggregates are presented. The old Smoluchowski’s theory for describing the kinetics of colloidal aggregation is revised using fractal concepts.
