Beskrivning av projektet
The use of supercritical carbon dioxide is an important part of green technology, since carbon dioxide can be used to replace of many poisonous chemicals. In the project, the usability of carbon dioxide in the modification of various surfaces for demanding industrial requirements was studied. The most significant results are the possibility to produce nanostructures on the surfaces of metallic zinc by controlled way using carbon dioxide as well as the possibility to post-process these structures for functional applications. It was found that the processed nanostructures on the surfaces of zinc plates enhance the adhesion between paint and metal, whereas the functional structures have been characterized to be photocatalytic features. The photocatalytic materials can be utilized, e.g., in antibacterial applications and in photovoltaic solar cells.
