S. Behrens: Liquid Crystal based magnetic hybrid materials
Description
By integration of magnetic nanoparticles in liquid crystalline matrices, mutual interactions between the magnetic nanoparticles and the molecules constituting the liquid crystal occur and soft, anisotropic nanocomposite materials with novel structures and properties will be available.
This project aims at investigating and synthesizing hybrid materials by controlled integration of magnetic nanoparticles in complex, liquid crystalline matrices. Initially, small nanoparticles with sizes that are compatible with the periodicity of the liquid crystalline phase and selected shapes (in particular anisotropic, magnetic nanorods) will be synthesized and integrated in the matrix.
Using a modular process, the surface properties of the nanoparticles will eventually be tuned by electrostatic charges or ligand-exchange reactions, enabling the embedding in the liquid crystalline matrix. As a start ionic liquid crystals and liquid crystals with low molecular weight will be examined and applied as matrix material, later on polymer liquid crystal will also be considered. Finally, the structure, phase behavior and magnetic properties of the materials will be analyzed.
