- design and preparation of polymer nanocomposites and protective coatings e.g. hydrophobic and/or superhydrophobic, oleophobic, self-cleaning, ‘easy-to-clean’, anti-graffiti and potentially anti-icing coatings
- coatings deposition using various techniques such as spin-coating, dip-coating or spray-coating
- surface texturization and functionalization by chemical modification from liquid or gas phase, surface activation using the low temperature air plasma system, polymer surface etching by air or oxygen plasma treatment
- testing of polymer materials, nanocomposites and coatings properties in particular the investigation of wettability, surface free energy and liquid-substrate interactions
We are currentyly looking for scientists with functional coatings expertise.
The scientific area of the Composite Materials & Coatings Group is focused on the development and characterization of composite materials and coatings with defined surface wettability properties for potential applications in industry (e.g. self-cleaning, anti-graffiti and anti-icing). Moreover, we provide assessment of the wettability properties, aging tests with the expertise in development of composite materials. We invite you to cooperation for applied and basic research projects.
The video summarizes the project “Technology development for the production of passive anti-icing systems based on innovative superhydrophobic epoxy nanocomposite coatings” financed under the LIDER IX program by the National Center for Research and Development.
Crucial for many industry and life aspects is passive anti-icing system production. Passive anti-icing systems do not need electrical energy to work. Adhesion reduction of super-cooled water droplets to the substrate in different weather conditions and thereby ice formation prevention (reduction of ice adhesion to the surface) is the main problem needs to be solved. Technology development of the superhydrophobic coatings with anti-icing properties preparation process is the aim of this project. Obtained superhydrophobic surfaces based on epoxy nanocomposites will be characterized by high efficiency in different weather conditions. This surfaces do not need electrical energy to efficient work. The superhydrophobic surfaces preparation technology developed in this project allows for simple industrial scale implementation.
The proposed research program has strongly application character with defined recipient of developed technology (aerospace and energy industry). The research have a high scientific value. The results of proposed research program are innovative:
– prepared innovative superhydrophobic coatings with anti-icing properties and high efficiency in different weather conditions.
Effectiveness of coatings deposited on the aircraft wing will be verified by: a) tests in wind tunnel with icing conditions b) tests during flight at an altitude of 1000 meters,
– new knowledge in superhydrophobic and anti-icing properties designing.
Currently used anti-icing systems need electrical energy to work, therefore the project has high commercialization potential.
