Abstract

Collapse pathways and dynamics of a semiflexible polymer in a poor solvent was investigated using three-dimensional Brownian dynamics simulation. It was found that there was a fast transition between the energy states of the polymer. It was observed that decay rate of uncollapsed states increased in the shear flow. The results show that direct formation of a torus and successive folding of the chain in progressively higher order racquets are the two possible pathways to achieve the stable conformation.
