Abstract

The microstructure and dynamics determine the final physical and chemical properties of macromolecules

and are of typical multiple length and time scale. The characterization of multi-scale structure and dynamics of polymers and their evolution at different length and time scale

and hence elucidation of their structure-property relationship is still a challenge in polymer science. Nowadays

solid-state NMR is a powerful tool in investigating the hieratical structure and complex motion in solid polymers at length scale from atom to 100 nm and time scale from 10

to 10s

and in elucidating the structure-property relationship. In this article

we will review the comprehensive multi-scale solid-state NMR techniques that we systematically constructed recently

and the application of these techniques in the study of polymer microstructure

segmental miscibility and interchain interaction

interphase and microdomain size

as well as the complex dynamics.
