摘要:
为探讨木质素/聚氨酯复合膜用做伤口敷料的可行性，将亲水型聚氨酯与Kraft木质素用溶剂分散和溶剂浇注挥发法制备了木质素/聚氨酯复合膜，并对复合膜进行了结构、外观及表面形貌、力学性能以及吸水性能的表征。结果表明，木质素/聚氨酯复合膜制备成功，表面光滑、质地均一；复合膜在干燥与湿润的状态下均表现出良好的力学性能：抗张强度分别为（9.4±1.6） MPa和（0.3±0.2） MPa，断裂伸长率分别为（1 107±67）%和（274±182）%；在去离子水中浸泡24 h后，木质素/聚氨酯复合膜的吸水率达（553.7±16.9）%，溶胀率为（653.7±16.9）%。所制备的木质素/聚氨酯复合膜满足伤口敷料的基本需求，是一种极具潜力的伤口敷料候选材料。
Abstract:
To explore the feasibility of lignin/polyurethane composite as a wound dressing，a lignin/polyurethane composite membrane was prepared by solvent dispersion and solvent casting. The structure，appearance，surface morphology，mechanical properties，water absorption and swelling ratio of the composite membrane were characterized. The results show that the lignin/polyurethane composite membrane is successfully prepared with smooth surface and homogeneous texture. In both dry and wet states，the composite membrane exhibits excellent mechanical properties with the tensile strength of（9.4±1.6）MPa and（0.3±0.2）MPa，and the elongation at break of（1 107±67）% and（274±182）%，respectively. After soaked in deionized water for 24 h，the composite membrane swells with water absorption of （553.7±16.9）% and swelling ratio of （653.7±16.9）%. The lignin/polyurethane composite membrane prepared meets the basic requirements of wound dressing，therefore is an excellent candidate material for preparing wound dressings.
