University of Graz
The Institute of Chemistry
The Institute of Chemistry of the University Graz is well known for research activities on polymer structure and surface properties (especially cellulose and its derivatives). The institute is looking back onto a long lasting cooperation with different industries; several of these mutual activities are the basis for new products and materials. The Institute has about 75 permanent staff members and approximately 30 PhD students; 1012 scientists are working on polysaccharides. The main expertise of the Colloid & Polymer Group is based on interface phenomena as well as surface modification and characterisation of synthetic, natural and biological materials. Further the modification and functionalisation of polymer surfaces, interactions of polymers with nano-particles, development of bio-compatible polymers, biosensors, membrane separation processes, the molecular-, structure-, surface- characterisation and rheology of colloids and polymers.
Description of the polysaccharide research activities:
- Modification of polysaccharide / cellulose surface in order to obtain specific and new material properties.
- Introduction of surface groups with specific functionalities using chemical, enzymatic and physical methods. Creation of surface layers of well-defined architecture in order to gain specific interaction properties.
- Development of new mechanical, physical, optical, drug storage and release and sensoric properties. This is obtained compounding and adsorbing nano-particles and functional polymers on polysaccharide surfaces.
- Development of cellulose membranes exhibiting specific interactions with components of the liquid phase (selective adsorption, separation).
- Enzymatic and chemical modification and characterization of polysaccharides according to their molecular properties (molecular weight distribution, hydrodynamic radii, branching).
- Development of three dimensional membranes and scaffolds for tissue engineering/ cell culturing
- Conservation and mass deacidification of paper.
- Preparation and stabilization of nano- micro particles and their surface modification for advanced biomedical and technical applications.
