VEGA 1/0811/21 (2021-2023), Protective hydrophobic coatings fabricated by plasma polymerization at atmospheric pressure, principal investigator
Hydrophobic surfaces are used in many applications due to their self-cleaning, anti-corrosion, and anti-icing properties. They can be formed using hydrophobic coatings in a number of ways, including the use of low-temperature plasma, which is an environmentally and cost-effective alternative to conventional chemical methods. In recent years, attention has been paid mainly to plasma technologies at atmospheric pressure, due to their simpler technical design and lower financial demands compared to low-pressure plasma. The project aims to study the preparation of hydrophobic or superhydrophobic layers on various surfaces by plasma polymerization at atmospheric pressure. Research will focus to clarify the plasma-chemical processes affecting the plasma polymerization process and a deeper understanding of the physico-chemical mechanisms responsible for the formation of a layer with optimal hydrophobic properties.

VEGA 1/0782/19 (2019-2021),The study of plasma-chemical processes in the preparation of inorganic nanofibers by method of plasma assisted calcination, the co-investigator
The aim of the project is study of plasma assisted calcination (PAC) in the preparation of inorganic nanofibers. The PAC of metal-organic fibers with the use of low-temperature plasma appears to be a prospective alternative to conventional thermal calcination. Thermal calcination is a high temperature (~100°C) long-term (several hours) process for removing of the polymer matrix and oxidation of precursor from polymer/precursor fibers to form inorganic nanofibres. Low-temperature non-equilibrium plasma is a chemically active environment, and with the use of a working gas with high oxidation potential, it is possible to produce ceramic nanofibers in significantly shorter time at lower temperature.

APVV-16-0216 (2017-2021), Modern plasma technologies for organic agriculture and food industry, the co-investigator
The project focused on the application of low-temperature plasma generated at atmospheric pressure for the treatment of biological material in agriculture and food industry for improvement of germination, growth dynamics and plant vitality, as well as for elimination of undesirable pathogenic microorganisms on the surface of seeds (and fruits). The use of low-temperature plasma is an environmentally and economically appropriate method for the gentle treatment of seeds of plants intended for sowing (cereals, legumes and others) and stored agricultural commodities (especially cereals, nuts, dried fruits) and for the human and animal nutrition and is a preferred alternative, or an additional method to the traditional treatment of seeds with chemical agents.

VEGA 1/0930/17 (2017-2019), Functionalization of polymer surfaces using plasma generated in liquids, the co-investigator
At present, the importance and use of polymeric materials in various applications requiring surface treatment (permanent hydrophilicity, antibacterial treatment, immobilization of functional groups, etc.) is constantly growing. Due to their thermosensitive nature, this is not an easy task. The development and construction of a non-equilibrium plasma source in a liquid medium using a high-voltage pulsed diaphragm discharge was an alternative method of surface treatment of polymer surfaces. The attachment of functional groups with the required properties to the polymer surface has been studied under different plasma generation conditions by modern surface methods and at the same time the physical mechanism of discharge in a liquid medium will be studied. New plasma treatment methods will enable the wider use of polymeric materials in many areas of the textile, automotive, construction and energy industries, such as functional and technical textiles, filter and carrier media, membranes and separators.
