摘　　要：采用相分离法制备了4种慈竹木质素酚(木质素对甲酚、木质素邻苯二酚、木质素间苯二酚、木质素邻苯三酚)。将4种木质素酚分别与聚羟基丁酸酯(PHB)共混制膜,探讨了木质素酚种类及用量对复合膜力学性能的影响,并对木质素对甲酚与PHB复合膜的吸水性和热学性能进行了分析。结果表明,现有工艺条件下木质素酚的最佳添加量应不超过10%;相同添加量下,木质素邻苯二酚和木质素间苯二酚与PHB的复合膜的力学性能好于木质素对甲酚和木质素邻苯三酚与PHB的复合膜。Four kinds of lignophenols （Lps） were prepared from native bamboo （ Sinocalamus Affinis） lignin through phase separation system by introducing p-cresol, catechol, resorcinol and pyrogallol to benzyl position of lignin respectively. The resulted lignophenols were characterized by FT-IR,^1H-NMR and GPC analysis, then they were blended separately with polyhydroxybutyrate （PHB） to cast thin biocomposite films at room temperature and atm pressure. The mechanical properties of the films were tested by TG and tensile strength instrument. The resuits indicated that, at the present process condition, the optimum adding amount of lignophenols was less than or equal to 10%. At the same condition, the films which introduced catechol and resorcinol were more suitable for the development of composite films because of the better mechanical properties.
