| Outline of Final Research Achievements |
Polymer gels, which consists of three-dimensionally cross-linked polymer chains swollen with solvents, are known to have inhomogeneous structure. The structural inhomogeneity in polymer gels has been studied extensively by scattering methods in inverse space. However, it has been difficult to obtain the quantitative information on the chain segment density from the inverse-space techniques. The objective of the current study is the development of novel methodology for the real-space analysis not only of the network structure but also local physical properties in polymer gels. We introduced a single molecule localization microscopy with a particle-tracking micro-rheology method to observe poly(N-isopropyl acrylamide) gels and succeeded the quantitative analysis of the network chain structure and dynamic viscoelasticity in a nanometric local area.
