In-situ Investigation of the shear-induced alignment of Diblock Copolymer Melts using Rheo-SAXS, Rheo-Dielectric and FT-Rheology

Meins, Thomas

Abstract:
In-situ flow alignment of self-assembled block copolymer melts have been investigated in detail under mechanical large amplitude oscillatory shear (LAOS) utilizing new and unique Rheo-SAXS and Rheo-Dielectric techniques. Significant correlations between the non-linear mechanical and dielectric responses were detected which strongly depended on the shear-induced structural changes. Furthermore, a novel de-orientation process was observed which is also observed via FT-Rheology and Rheo-Dielectric
