Using Modified DLA Model Simulation of the Form of Copolymer Flower-Like Aggregation
Keyword(s):
In this papper, based on the study of basic algorithm of fractal DLA model, the standard DLA model was modified by setting the parameters, and the PS-b-PAA block copolymer representating a kind of flower-like aggregation was taken as the research object. Through observating the growth characteristics of this kind of flower-like aggregations formed in different external conditions, their fractal characteristics were determined by box-counting method. Then the modified DLA model combined with the image processing technology was used to simulate this kind of flower-like aggregations. Finally, the simulated results were evaluated through visual observation and fractal dimension.
