Bubble nucleating and porosity were improved by adding lignin granule, and cell size of the polyurethane foam was decreased. Not only physical property but also thermal property of the material were enhanced. Compared with soft polyurethane foam, tensile strength of lignin reticulated polyurethane foam was raised by 140% at most which lignin content was 5%, and the heat-degradation temperature at the first stage was 50℃ more than soft polyurethane foam which lignin content was 10%. There had been a great improvement in heat resistance of the material. It was showed that weight of biological film reached to 10000 mg/L and 12100 mg/L when the lignin content of the polyurethane foams was 5% and 8% respectively via 30-day biofilm formation testing.
