A facile method for generating worm-like micelles with controlled lengths and narrow polydispersity.

This work shows that highly uniform worm micelles formed by polymerisation induced self-assembly can be obtainedviasimple post-synthesis sonication. Importantly, this straightforward and versatile strategy yields exceptionally monodisperse worms with tunable aspect ratios ranging from 7.2 to 17.6 by simply changing the sonication time.
