Short disctoption of the project:

The main aim of this project is improving the manufacturing process of aerogel structures employing advanced 3D printing technologies. This project will be based on three main aspects, namely: 1) synthesis of high-performance photoinitiators for initiating cationic or hybrid Photopolymerization, 2) optimization of 3D printing parameters in DLP technology from photocurable resins containing newly synthesized high-performance photoinitiating systems, 3) selection of the most suitable drying method for the obtained aerogel structures. In the first stage of the research, a detailed study of the obtained photoinitiators is planned to understand their spectroscopic, photochemical, photophysical and electrochemical properties. Further stages of the research will focus on 3D printing experiments, as well as on optimization of printing parameters. Subsequent stages will be directly related to aerogel structures (selection of drying method, obtaining porous structure, porosity testing). It is expected that the result of this project will be the development of new compounds for the role of cationic photoinitiators, whose absorption characteristics will be compatible with the emission characteristics of light sources used in DLP printers. In a further stage of research, the newly developed photoinitiators are expected to produce highly porous aerogel structures. The interdisciplinary character of the undertaken research problem will allow to significantly broaden the knowledge of organic chemistry, especially material engineering and photochemistry.
