Nanoscale Study of Polymer Dynamics.
The thermal motion of polymer chains in a crowded environment is anisotropic and highly confined. Whereas theoretical and experimental progress has been made, typically only indirect evidence of polymer dynamics is obtained either from scattering or mechanical response. Toward a complete understanding of the complicated polymer dynamics in crowded media such as biological cells, it is of great ...

متن کاملSwelling-induced folding in confined nanoscale responsive polymer gels.
Mechanical instabilities such as buckling, wrinkling, creasing, and folding are commonplace in both natural and synthetic systems over a wide range of length scales. In this study, we focus on the spontaneous folding behavior of the highly swellable confined nanoscale (thickness below 100 nm) gel films resulting in the formation of a network of regularly folded structures spontaneously emerging...
متن کاملSelf-Oscillating Structural Polymer Gels
Self-oscillating polymer gel has become a distinguished class of smart soft materials. Here we fabricated and demonstrated a self-oscillating structural gel network with the incorporation of the Belousov-Zhabotinsky (BZ) reaction. The structural polymer gel oscillates at a macroscopic level with remarkably faster kinetics compared to a normal gel of similar chemical compositions. The structural...
متن کاملA Molecular Theory of Polymer Gels
A new theory for polymer gels is developed on the basis of the single-chain mean-field (SCMF) theory. This theory takes the mesh chain or the star polymer as the characteristic unit of polymer gels, and it allows the study of chain conformation properties for gels in their different states. The preparation condition effect is conveniently described by the current theory, and the gels with compl...
