以微晶纤维素和苯基异氰酸酯为原料,合成了纤维素-三(苯基氨基甲酸酯)(CTPC)手性高分子,并以CTPC为膜材料用无纺布做支撑,制备了CTPC复合膜.讨论了浓度、操作压力对膜的性能的影响,并测试了复合膜的机械性能.将CTPC复合膜初步应用于对映体(±)-1-萘乙醇的分离.结果表明:当使用质量浓度为12%的复合膜,操作压力为0.25MPa时,该膜对(±)-1-萘乙醇具有明显的选择性,此时复合膜的抗张强度和断裂伸长率分别为bδ=45MPa,εb=54%.
Cellulose and phenyl isocyanate as raw materials, cellulose - tris (phenyl carbamate) (CTPC) chiral polymer synthesis, and CTPC film material with non-woven fabric support prepared CTPC The effects of concentration and operating pressure on the properties of the films were discussed and the mechanical properties of the films were tested.The CTPC films were initially applied to the separation of enantiomers (±) -1-naphthyl alcohol.The results showed that When using the composite membrane with 12% mass concentration, the membrane has obvious selectivity to (±) -1-naphthylethanol when the operating pressure is 0.25MPa. The tensile strength and elongation at break of the composite membrane are bδ = 45 MPa, εb = 54%.
