    Abstract

    Orientational order and spatial distribution of anisotropic nanoparticles in the lamellae phase of block copolymers have been considered in the case of strong segregation taking into account both isotropic and anisotropic interaction between nanoparticles and the polymer chains. Explicit analytical results have been obtained for the distribution of anisotropic nanoparticles in the lamellae phase and the nematic order parameter profiles have been calculated numerically. It has been shown that anisotropic nano-paticles are orientationally ordered in the boundary region between the blocks and the nematic order parameter possess opposite signs in different blocks.
