What is Cyclic vs Linear Bottlebrush Polymers in Solution: Side-Chain Length Effect about?
Bottlebrush polymers (BBPs) of different architecture are of considerable interest for a broad range of applications, including nanomedicine, electronics, and self-healing materials. Using atomistic molecular dynamics simulations, we investigate and compare the structural and hydration properties of cyclic and linear poly(vinyl alcohol)-graft-poly(ethylene oxide) (PVA-g-PEO Nd sc ) BBPs in aqueous solution as functions of PEO side-chain length, N sc . We find that overall cyclic BBPs are smaller than the corresponding linear BBPs and their shape changes from donutlike to disklike to starlike with increasing side-chain length, while linear BBPs vary in shape from an expanded coil to a rod/cylinder. The radius of gyration of cyclic BBPs increases with an increase of the side-chain length at a somewhat slower rate than the linear BBPs but follows the same scaling R g ∼ N sc 0.58 in the limit of long side chains. For short grafts, we determine that the persistence length, l p , for both cyclic and linear BBPs increases in a similar manner following an l p ∼ N sc 0.54 dependence. In the long side-chain limit, the persistence length (l p ) of cyclic BBP saturates, while for linear BBPs l
