Investigation of Multiscale Molecular Dynamics in Polymer Solids: Sold-State NMR Approachs

Abstract

Abstract:

Solid-state NMR is an important and powerful tool for studying the structure and molecular dynamics of solid polymer. There are many solid-state NMR methods that can be used to illustrate the details of molecular dynamics occuring in a wide frquency range from Hz to MHz. These methods have been commonly used to study of the multiscale molecular dynamics in polymer solids. In this article, the NMR principles for studying the molecular dynamics of different time scale were briefly reviewed, as well as the structure and multiscale molecular dynamics features in polymer solids. Several examples were presented to show how solid-state NMR methods can be used to investigate the multiscale molecular dynamics in polymer solids.

Key words: solid-state NMR, molecular dynamics, polymer solids, conformation transformation, chain diffusion
