Synthesis of new bio-polyols in Adam Olszewski’s research - a graduate of the Doctoral School
–Currently, there is a growing demand for polymer materials that do not contain petrochemical raw materials. This is particularly important in the case of polyurethanes (PU), as the two main substrates required for their synthesis, that is polyols and isocyanates, come mainly from petroleum sources – explains Adam Olszewski.
A number of methods have been developed so far to mitigate the impact of PU on the environment. One of them is the process of liquefaction of biomass, which enables the synthesis of bio-polyols (BP).
Despite the benefits for the environment, BPs have not yet found wide application. This is mainly due to their not fully defined properties, specific color and smell. For this reason, further research is necessary to fully characterize the liquefaction process and the properties of the obtained BPs. Although selected BPs were tested in polyurethane foams (PUFs), there remains a lack of comprehensive knowledge on the effect of BPs on the properties of PUFs and their application in other types of materials. Therefore, in his research work the PhD student focused on the synthesis, properties and application of new polyols obtained in the biomass liquefaction process.
The result of this research is the doctoral thesis "Synthesis, properties and application of new bio-polyols obtained as a result of biomass liquefaction", prepared under the supervision of Dr. Hab. Eng. Łukasz Piszczyk from the Faculty of Chemistry.
– My research allows for better management of biomass waste, which often poses a troublesome waste for businesses - says the scientist. - Polyurethanes produced with the participation of BP can be, among other things, a component of materials used for thermal insulation of buildings, adhesives and polymer-wood boards, commonly used in furniture production. It is a healthier alternative to traditional wood-based materials, where formaldehyde is harmful to health.
Adam Olszewski continues research on the application of the obtained polyols as part of the national project PRELUDIUM 22, but also as part of international cooperation, as recently, together with his supervisor, they have joined an international consortium in the HORIZON program. His academic portfolio already includes 20 scientific articles, more than half of which were created in cooperation with national and international research centers.
Despite various activities, including involvement in the local government, Adam Olszewski primarily identifies himself as a scientist and wants to develop his career path in this direction. Therefore, taking up studies at the Doctoral School was a natural choice for him, one he would make again. During his studies, he felt a lack of broader cooperation with industry, so that research could be translated into implementation faster. However, it was the second-cycle studies that gave him the opportunity to meet many scientists from different disciplines and gain a broader perspective on research work.
– A doctorate also involves many soft skills that are rarely mentioned: public speaking, networking at conferences, passing on knowledge to students and working for others – adds the scientist.
