Methods and technical resources


  • Light microscopy (LM), also 3D
  • High resolution field emission scanning electron microscopy (FE-SEM)
  • Atomic force microscopy (AFM)

Special methods

  • Spectroscopic ellipsometry
  • Electron spin resonance (ESR)
  • UV/VIS spectroscopy
  • MALDI-TOF / TOF mass spectrometry
  • Quartz oscillator microbalance with dissipation monitoring (QCM-D)

Surface tension/wettability

  • Static and dynamic contact angle measurements, various tensiometers e.g. according to Wilhelmy, du Noüy, dynamic drop-volume or bubble-pressure
  • Adsorption / desorption curves (BET surfaces, pore radius distribution)
  • Gel permeation chromatography (GPC)

Characterization of polymers and particles

  • Dynamic light scattering (DLS)
  • Zeta potential
  • Particle size distribution
  • Adsorption / desorption isotherms (BET surfaces, e.g. with IGA)
  • Thermogravimetric analyses (TGA)
  • Dynamic difference calorimetry (DSC)
  • Microcalorimetry (μ range)
  • Gel permeation chromatography (GPC)
