Biodegradable polyester-based polyurethane foams

A biodegradable foam includes a mixture of a polyester-based polyurethane foam and a soil-dwelling carbon-digesting bacterium embedded in a carrier compound. The mixture of the soil-dwelling carbon digestion bacteria is uniformly dispersed in the whole polyester-based polyurethane foam. The biodegra...

Beschreibung
Zusammenfassung:	A biodegradable foam includes a mixture of a polyester-based polyurethane foam and a soil-dwelling carbon-digesting bacterium embedded in a carrier compound. The mixture of the soil-dwelling carbon digestion bacteria is uniformly dispersed in the whole polyester-based polyurethane foam. The biodegradable foam shows a higher biodegradation rate than the polyester-based polyurethane foam which does not contain the soil-dwelling carbon digestion bacteria. 可生物降解的泡沫，其包括聚酯基聚氨基甲酸酯泡沫和由包埋在载体化合物中的土栖碳消化细菌组成的混合物。所述土栖碳消化细菌的混合物均匀地分散在整个所述聚酯基聚氨基甲酸酯泡沫中。这种可生物降解的泡沫显示出比不含土栖碳消化细菌的聚酯基聚氨基甲酸酯泡沫更高的生物降解速率。
