Coatings & Colloids (CoCo) Group

Research focus:
Polymeric materials and processes (PMP)

The CoCo group deals with an applied material and processes science which overlaps with classical chemistry and exhibits potential synergies with the faculty of Mechanical Engineering, well established at the University of Paderborn. This holds true especially for the generation and functionalization of particles, the technology of glues and binding, as well as for the development of new heavy duty and high-tech polymers. The industrial process "coating", i..e. the synthesis, application, technology of equipment and plant and especially the choice and development of raw materials is studied in its interactive dependencies. Essential milestones are

the generation of anisometric polymeric nanoparticles and regular 3D-networks out of them (see fig.1),
the substitution of chromates in pre-treatments of metal surfaces for corrosion protection (see fig. 2),
the bio-inspired use of structural hierarchies for optimization of material properties.

In this context, examples of recently performed projects are

Easy-to-Clean-coatings for concrete surfaces as well as for automobile rims (this project has been honored with an industrial research transfer award),
the substitution of environmentally harmful solvents in wire coatings (see fig. 3),
the synthesis of high-temperature resistant metal/polymer compounds.

Teaching:

The CoCo group is responsible of an own study path:
"Chemistry and Technology of Coatings". Students performing this path finish consecutively as Bachelor or Master Sci., respectively. In addition, a doctorate may follow the Master studies depending on one’s personal skills. In this respect, the CoCo group exhibits a unique characteristic within the landscape of German universities.
