The Center for Multi-Scale Characterization offers the institute access to methods of structural and morphological characterization of polymer and hybrid materials over length scales from nanometers to millimeters. The range of methods allows to obtain the following information:

• The morphology in polymer materials, polymer composites and thin films ranging from nanometers to micrometers is examined by electron microscopy (SEM and TEM) and by atomic force microscopy (AFM).
• The chemical composition is obtained from analytical electron microscopy (EFTEM, EELS, EDX) spatially resolved on the nanoscale and as a sample medium from solid-state NMR, on length scales over 100 μm by NMR microscopy. By combining pulsed field gradient NMR, flows are mapped. The size of molecules and complexes up to 50 nm is accessible from diffusion NMR, while the effective charge is determined from electrophoresis NMR.
• Molecular dynamics can be obtained from NMR methods over a wide range of correlation times.
