In the example of study of insulating polymer foams we demonstrated an application of the Terahertz spectroscopy and imaging. Based on THz imaging method we analysed the macroscopic structure of foamed polymer materials, including the analysis of air gaps, inclusions, beads and voids distribution. From THz spectroscopic constants we evaluated the density of foams and IR radiation absorption. We demonstrated that THz methods enable both chemical and structural characterization of foamed polymers. This paper contains primarily results of the project and partially also results of the program New imaging and analytic methods.

This contribution presents results of THz imaging of foamed polymers with with our system for THz spectroscopy and imaging, which was developed within this project. We demonstrated that various polymer foamed materials feature low absorption in the THz region which makes THz-TDS and TPI viable methods for characterizing the structure of foamed materials in a submillimetre-scale resolution. Thus, THz methods can be used as a complementary or alternative method to electron microscopy and X-ray microtomography.

This contribution describes effects of graphene on liquid-crystalline blue phases and a study of these systems with high energy X-Ray Small Angle Scattering. This paper is partially related to the project, which plans to characterize liquid crystalline systems after the completion of the temperature chamber.
