How to interpret the radius of gyration in case of polymer blend?

13 January 2018 1 532 Report

I did the SAXS analysis of my samples and came across this term.

Dear all,

the radius of gyration is a rough approximation on the 3D dimension of a macromolecules. It the minimum radius sphere that surrounds the macromolecules. It is thus a measure of the contraction/extension of a macromolecule under a given environment. In your case a blend. Regards
