The team conducts research at the Centre for Organic and Nanohybrid Electronics (CONE) and the Department of Physical Chemistry and Technology of Polymers, Faculty of Chemistry (RCh4), Silesian University of Technology. The group specializes in (1) functionalization (modification) of surface of materials applying (electro)chemical methods, and in (2) surface characterization using spectroscopic, electrochemical and microscopic techniques. The main area of interest the formation of organic layers for application in photochemical processes and in (opto)electronic devices.
Photoactive organic layers
The team conducts research on deposition of photoactive organic layers by (electro)chemical grafting and electrochemical polymerisation. The main objective of the research is formation of organic layers capable of producing reactive oxygen species (ROS), especially singlet oxygen, which can be used in photocatalytic processes (e.g. synthesis of fine chemicals) or as antimicrobial coatings.
