Soft matter research

Soft matter research includes several different systems, from confined liquid crystals (in planar, cylindrical, spherical geometries or even HPDLCs) and observations of surface effects, to self-assembly of guanosine and investigations of polymeric aligning layers using optical methods.

 

Supramolecular assembly in solutions of dics-shape molecules

The research is presently focused on determination of the size, shape and interaction properties of the self-assembled molecular aggregates formed in isotropic columnar phase of guanosine derivatives in aqueous solutions.

 

 

 

 

 

Structural and dynamics properties of holographic polymer dispersed liquid crystals

Profile of nematic director field and electrooptic response of various types of periodic polymer dispersed liquid crystal media are investigated. The emphasis is presently on holographically formed gratings and on periodic structures achieved by the use of periodic electrode schemes.

 

Thin films of organic molecules on solid substrate

Various methods to obtain aligned surface layers of polymeric and biological molecules on solid substrates are studied by surface sensitive non-linear optical techniques. The research is presently focused on photosensitive and electrically commanded polymer surfaces.

 

 

 

 

Anchoring energy of liquid crystals on polymeric substrates

Azimuthal and zenithal anchoring coefficients are measured using dynamic light scattering. Thermal fluctuations spectra in nematic samples are observed and thus no external torque acts on the liquid crystal during the measurement.
