Open-Cell Aliphatic Polyurethane Foams with High Content of Polysaccharides: Structure, Degradation, and Ecotoxicity
Original language description
The influence of starch and 2-hydroxyethyl cellulose (HEC) additives on structure, properties, ecotoxicity and (abiotic and biotic) degradation of fully aliphatic (isocyanurate ring-based) polyester-ether polyurethane (PUR) foams is studied. These PUR foams are designed as hydrophilic open-porous materials predisposed to enzymatic hydrolysis with potential application as cellular carriers and alternative nutrient source for activated sludge in wastewater treatment plants. In comparison to the neat (non-modified) PUR foam, the PUR foams with incorporated starch and HEC modifiers exhibited tougher character and slightly increased open-cell content but on the other hand significantly coarser cellular structure with much larger cell size and reduced water absorption. The progress of 6-week abiotic hydrolysis is characterized in detail showing almost a complete decomposition of ester groups, a partial degradation of urethane linkages and fully intact isocyanurate ring. The extent of biodegradation by means of bacteria was very similar for all tested PUR foams, while the fungi biodegradation took place faster for starch and HEC modified PUR foams. However, the leachates from both starch and HEC modified foams exhibited significantly higher ecotoxicity than the leachates from the non-modified PUR foam.
