Scattering from supramacromolecular structures

By Carlos I. Mendoza and Carlos M. Marques


We study theoretically the scattering imprint of a number of branched supramacromolecular architectures, namely, polydisperse stars and dendrimeric, hyperbranched structures. We show that polydispersity and nature of branching highly influence the intermediate wavevector region of the scattering structure factor, thus providing insight into the morphology of different aggregates formed in polymer solutions. Typeset using REVTEX Scattering by light, x-rays or neutron radiation provides a fundamental tool to investigate the shapes and statistical nature of large molecules in solution [1]. For objects of fixed shape, like spherical, ellipsoidal or cylindrical colloids, the scattering functions are known and can easily be compared to experimental data, thus allowing for a determinatio
