Abstract

Understanding colloidal aggregate structures and formation is one of the central issues of colloid science and an important topic in many industrial, biological and environmental processes. Owing to the complexity of these mechanisms, aggregate formation is still difficult to investigate experimentally. Computer simulations provide a qualitative and quantitative means of understanding the factors that influence particle-particle interactions by (i) viewing the graphical output throughout the course of the simulation, which is invaluable for revealing the complex series of events that occur in the solution (ii) allowing the calculations of quantitative features that characterize the solution (iii) permitting a systematic alteration of various factors, and consequently the examination of how such factors affect both the kinetics of aggregation and aggregate structures. The object of this paper is to review the basic computational aggregation models of colloidal particles and polymers and their developments. Scaling and fractal concepts allowing the quantitative description of the aggregate structure are introduced and the influence of aggregation mechanisms on the structure of the resulting aggregates is discussed.
