Identification of flow and structure properties by combining small angle light scattering (SALS) and rheology

Rheological measurements provide information about the macroscopic behavior, but cannot give further information about the inner structure of a sample. The macroscopic behavior usually depends on the microscopic structure. Conclusions from rheological measurements on the microstructure are based on observations of model systems.

Introduction

Rheological measurements provide information about the macroscopic behavior, but cannot give further information about the inner structure of a sample. The macroscopic behavior usually depends on the microscopic structure. Conclusions from rheological measurements on the microstructure are based on observations of model systems.

The combination of a small-angle light-scattering device (Anton Paar Rheo-SALS) and an Anton Paar rheometer permits, by integration of the optical method, direct correlation between the rheological behavior and the microstructure of the sample.
