| Description |
Fully aliphatic biodegradable polyurethanes (PUR) are mainly used in environmental technologies such as biofilters, sorbents, carriers of biomass in bioreactors, etc. However, a certain stability is required for these materials because frequent replacement of unstable material is not environmentally and economically beneficial. Based on knowledge of self-degradation mechanisms in biodegradable polyester-ether PUR materials can be prevented by adding effective natural additives during preparation. Therefore, this project will firstly focus on the preparation of new biodegradable PUR materials with extended lifespan. The second research objective will focus on comparing properties of PUR materials (physical-mechanical, thermal, macroscopic properties, etc.) with reduced and extended lifespan. The third part of this work will be included the analysis and monitoring of accelerated aging in newly synthetized PUR materials under abiotic conditions (hydrolysis, UV aging, etc.). The last part will monitor the comparison of PUR materials biodegradation rate with reduced and extended lifespan. |
