Despite fundamental and technological interest in these materials, only a handful of experimental phase diagrams exist due to the laborious task of preparing such diagrams. In this work, two copolymer series are each synthesized from a single macromolecule via sequential living anionic polymerization to yield molecularly asymmetric diblock and triblock copolymers systematically varying in composition. The phase behavior and morphology of these copolymers are experimentally interrogated and quantitatively compared with predictions from mean-field theories, which probe copolymer phase behavior beyond current experimental conditions.}, number={23}, journal={POLYMER}, author={Gozen, Arif O. and Gaines, Michelle K. and Hamersky, Mark W. and Maniadis, Panagiotis and Rasmussen, Kim O. and Smith, Steven D. and Spontak, Richard J.}, year={2010}, month={Oct}, pages={5304–5308} }

In this work, dynamic rheology is used to probe the frequency and thermal responses of nanocomposites composed of a symmetric poly(styrene-b-methyl methacrylate) (SM) diblock copolymer and varying in nanoparticle concentration and surface functionality. At sufficiently high loading levels, FS nanoparticle aggregates establish a load-bearing colloidal network within the copolymer matrix. Transmission electron microscopy images reveal the morphological characteristics of the nanocomposites under these conditions.}, number={10}, journal={NANOSCALE RESEARCH LETTERS}, author={Gaines, Michelle K. and Smith, Steven D. and Samseth, Jon and Khan, Saad A. and Spontak, Richard J.}, year={2010}, month={Oct}, pages={1712–1718} }
