Polymer Chemistry
Polymer Chemistry (Polymer/Colloid Science and Engineering)
research at Stony Brook is centered around the investigations of polymer
structures, morphologies and dynamics from atomic, nanoscopic, microscopic to
mesoscopic scales. The current research topics include fiber formation and
deformation at nano- and micro-scales, high pressure study under supercritical
conditions, mineralization under polymer nanostructured templates,
organic/inorganic hybrid nanocomposites, phase transitions of polymers,
polymer/DNA interactions, new polymer media for DNA electrophoresis, polymer
crystallization, polymer melts and solutions during flow, supramolecular
synthetic and biological molecules. Recently, several major research programs
in collaboration with the faculty of Biomedical Engineering Department and of
Medical School have also been launched to apply the bioabsorbable/biocompatible
polymers for medical applications, drug delivery and tissue engineering.
Our laboratories are equipped with some best nanostructure
characterization facilities in the world, including laser light scattering
laboratory at Stony Brook and synchrotron X-ray scattering beamlines at the
National Synchrotron Light Source in Brookhaven National Laboratory and at the
Advanced Photon Sources in Argonne National Laboratory. The fundamental light
scattering techniques involve photon correlation spectroscopy, transient
electric birefringence, fluorescence recovery after photobleaching, and
holographic relaxation spectroscopy. Together with time resolved simultaneous
small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD)
techniques and other methods such as Raman scattering, we have been studying
many frontier polymer research problems as stated above.
