Abstract

We study the problem of a semi-flexible polymer brush immersed in a poor solvent and show that the brush is unstable to collapse. We are able to solve the problem exactly by mapping it onto one of a classical particle in a known potential. In contrast to the case of flexible chains, the free-energy costs of bending may result in a sharp transition to a stable tilted and bent phase.
