Apolymer material shows unique physical properties such as viscoelasticity.
The origin of the various characteristic properties of polymers is the
large degree of freedom of individual molecule, which has a long chain-like
shape with large molecular weight. Therefore, the direct information of the
conformation and dynamics of a single polymer chain is a key to understand the
fundamental aspect of polymer physics. The most powerful method to observe
single polymer chains is the fluorescence imaging of the dye-labelled polymer
chain dispersed in the unlabelled polymer matrix. However, the information
from the fluorescence microscopy has been limited because the structure
smaller than 200 nm cannot be observed by optical microscopy because of the
diffraction limit of light. Recent development of optical microscopy enabled
the fluorescence imaging with the high spatial resolution of ~10 nm beyond the
diffraction barrier. We employed the super-resolution fluorescence microscopy
to study the structure and dynamics of polymer materials at the single
chain level. The current talk deals with the principle of the super-resolution
microscopy for polymers and its application to investigate the conformational
dynamics of single polymer chain in macroscopic deformation processes.
Biography
Hiroyuki Aoki is a Senior Scientist in Materials and Life Science
Division, J-PARC Center, Japan Atomic Energy Agency. He
obtained his degrees of BE, ME, and PhD from Kyoto University
in 1996, 1998, and 2001, respectively. He became an Assistant
Professor of Department of Polymer Chemistry, Kyoto
University in 2001 and promoted to an Associate Professor in
2006. In 2016, he moved to J-PARC as a Senior Scientist. His
research interests are focused on structure and dynamics
of polymer materials at the single molecule scale. He was
awarded Inoue Research Award for Young Scientist from Inoue
Foundation for Science (2002), Young Scientist Lectureship
Award (2008), SPSJ Award for the outstanding paper inPolymer
Journal (2008), and SPSJ Science Award from Society of
Polymer Chemistry, Japan (2016).
