Abstract
The effects of random bond breaking on cluster–cluster aggregation have been investigated using both 2d and 3d simulations. A combination of random bond breaking with the normal cluster–cluster aggregation process produces structures which are more compact on short length scales and contain many loops. However, the fractal dimensionality of the aggregates is increased only slightly, if at all, by random bond breaking. Fast bond breaking rates have the largest effect on short length scale structure, but the effect on the structure at larger length scales is quite small. Fast bond breaking leads to the formation of many small loops but intermediate and slow bond breaking rates lead to the formation of larger loops.
