摘　　要：木质素是自然界中第二大可再生资源,它是一类复杂的、非结晶的、三维网状酚类高分子聚合物。将木质素引入到聚氨酯薄膜材料中,既提高了薄膜的使用性能和应用范围,又提高了木质素资源的附加值。从未改性木质素聚氨酯薄膜和改性木质素聚氨酯薄膜两方面综述了近年来木质素在聚氨酯薄膜制备中的应用,并展望了该领域的发展趋势。lignin, as the second largest regeneration resource in nature, is a complex, non-crystalline and tridimensi- nal net structure polymer. The preparation of polyurethane film with lignin does not only improve the film performance and its range of applications, but also does increase the value-added application of lignin. Research progress with respect to poly- urethane film with modified and unmodified lignin was reviewed. Furthermore, the tendency of the development in this field was also prospected.
