ORIENTATIONAL ORDERING OF POLYMERS ON A FLUCTUATING FLEXIBLE SURFACE

Arguments are presented to the effect that embedding semiflexible (wor mlike) ideal polymers into a fluctuating, flexible surface leads to an effective attractive orientational interaction between polymer segmen ts that precipitates an orientational ordering transition of the polym er chains on the surface even in the case of otherwise ideal (noninter acting) chains. The orientational interaction is analogous to the (zer o order) Casimir force and is due to the energy change in surface conf ormational fluctuations in the presence of embedded semiflexible chain s.
