中文摘要: |
以棉浆纤维(CF)为基底材料,Zr6O4(OH)4(BDC)6(UiO-66)为金属有机骨架材料(MOFs),采用水热合成法制备了UiO-66/CF;利用磷酸正十八酯(OPA)改性UiO-66/CF,在其表面引入疏水烷基链,合成了OPA-UiO-66/CF,并对其表面形貌、结晶结构、疏水亲油性能等进行了分析表征。结果表明,UiO-66可均匀负载在CF表面,且生长在CF表面的UiO-66晶体粒径是纯相UiO-66晶体粒径的1/10;OPA-UiO-66/CF具有疏水亲油性能,对油包水乳液的分离效率可达99.6%。 |
Abstract: |
UiO-66/CF was prepared by hydrothermal synthesis method with cotton pulp fiber (CF) as the base material and Zr6O4(OH)4-(BDC)6 (UiO-66) as the metal organic framework material (MOF). UiO-66/CF was modified by octadecylphosphonic acid (OPA) to introduce hydrophobic alkyl chains on its surface so as to synthesize OPA-UiO-66/CF. The surface morphology, crystal structure, and hydrophobic & lipophilic properties of OPA-UiO-66/CF were analyzed and characterized. The results show that UiO-66 can uniformly load on the surface of CF, and the particle size of which is 1/10 of that of pure UiO-66. OPA-UiO-66/CF is of hydrophobic & lipophilic properties with separation efficiency for water-in-oil emulsions up to 99.6%. |
