Nanoparticle-copolymer composites: Curvature

The compression coefficient and the mean curvature coefficient of a composite of an A-B diblock copolymer charged with nanoparticles depend on the concentration of nanoparticles and on the dissymmetry of the copolymer chains. Concerning the curvature coefficient, a distinction must be done between an adiabatic and an isotherm coefficient when the copolymer chains are not symmetric or when Phi is not zero. Finally, the AB interfaces of the composite film present a spontaneous curvature that we calculate in the approximation of ''small'' nanoparticles.
