  1. Polymer Networks Containing Reversibly Associating Side-GroupsMitchell Anthamatten, University of Rochester, DMR 0906627 Architecture Matters: Dynamic Mechanical Properties Polymers bearing multiple-hydrogen bonding side-groups exhibit unique viscoelastic properties and are enabling new approaches to shape memory polymers, self-healing interfaces, and thermoplastic elastomers. To explore how polymer architecture impacts shape memory properties, we synthesized and characterized a series of polymers bearing different amounts of thermo-reversible and photo-crosslinkable side-groups. We discovered that the presence of a chemically crosslinked network strongly supports cooperative reversible binding of side-groups. This finding will spur development of shape memory elastomers with stronger recovery forces.

  2. Polymer Networks Containing Reversibly Associating Side-GroupsMitchell Anthamatten, University of Rochester, DMR 0906627 • NSF Funding Supported: • Development of twonew “Green Engineering” workshops for local secondary school teachers to highlight national science & technology in the area of energy and the environment. • fuel cells • global warming & CO2 sequestration • Training of two PhD students who will establish careers in industrial research: the first, Jiahui Li completed his PhD in July, 2011. • Acquisition and installation of shared research instrumentation (see left) also used for undergraduate training through the PI’s Soft Matter course. Acquired & setup a solid-state rheometer (instrument donated by Rohm & Haas) external liquid nitrogen coolingenables low temperature studies
