| Abstract: | The plants with nature fiber liquefaction in polyethylene glycol, polyester polyol and the modified polyurethane preparation were reviwed. The properties and application of plant fiber,corn stover, wheat straw, bagasse fiber and bark modified PU were introduced. Briefly the water resistance, anti-bacterial action, thermal stability of PU made from tannin were discussed. These plants could substitute some of the polyols from the petroleum through by liquefaction. It was suggested that they could be used in PU fields such as sanitation, furniture and packaging of food. |
