    The role of polymers in stabilizing liquid crystal (LC)-water interfaces is well studied but how the LC affects stabilizers is not fully explored yet. Here, Ma et al. show that amphiphilic polymers change their behavior when the LC is heated towards its transition to the isotropic state, and propose that this is due to an entropic repulsion active at low temperatures where the orientationally ordered LC restricts the mobility of the flexible polymer chains.
