Development of multifunctional complex fluids (formulations) for coating semi-porous surfaces
Prepare multifunctional formulations containing various functional agents which have high affinity to natural and/or synthetic smooth (foils) and semi-porous (textile) materials, and to multi-functionalize the materials by the formulations including nanoparticles with specific properties using wet-chemical and ink-jet printing process.
Originality and innovative aspects: Intensive development of nanotechnology linked with generation of nanostructures and nanomaterials offers great possibilities of creating modern multifunctional materials. Such materials based on semi-porous surfaces, e.g. textile substrates, can have very wide applications due to the new properties and functions rendered to these substrates such as self-cleaning, anti-bacterial, UV protection, flame resistance, super hydrophobicity, electrical conductivity, friction and wear resistance, environmental purification, pH/thermo-responsive hydrophobicity or hydrophilicity. The ultimate impact of nanotechnology in the area of textile and other potential application areas will depend on the type and structure of nano-structured functional agents and their coating process. The nano-structured functional agents will include TiO2 nanoparticles, titania nanotubes, silver nanoparticles, gold nanoparticles, zinc oxide nanoparticles and nanorods and copper nanoparticles. Among established wet-chemical modifications processes, inkjet printing techniques will be used as a novel approach with high efficiency and low cost to deposit functional agents on fabric surfaces.
Methodologies: The 2D and 3D rheological behavior of printable complex liquids as well as their spreading behavior over semi-porous randomly rough surfaces will be studied. The ESR will work in a close collaboration with associated industrial partners TANATEX and VEROSOL. The experimental data will be compared with the simulation results of TUD
