以四(三苯基膦)钯为催化剂,N,N-二甲基甲酰胺为溶剂,通过三(4-硼酸频呢醇酯苯基)胺与3,6-二溴咔唑的Suzuki偶联反应合成了一种超疏水多孔有机聚合物LNU-40.该聚合物的比表面积为32 m2/g,具有良好的热稳定性且在常见有机溶剂中不溶解或分解.LNU-40具有较低的表面能和152.4°的水接触角,表现出较好的酸碱环境抵御能力,能够制备具有优异自清洁性能的超疏水表面.使用LNU-40制成的超疏水柔性织物对有机溶剂的分离效率可达90%以上,对油的吸附能力可达其自身质量的3~8倍,吸附分离性能优越,可用于石油化工、食品及制药等行业含油等有机溶剂废水的油-水分离处理.
Preparation and Oil-water Separation Performance of Superhydrophobic Porous Organic Polymers
A superhydrophobic porous organic polymer denominated as LNU-40 was synthesized via a Suzuki coupling reaction of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-N,N-bis[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]aniline,3,6-dibromocarbazole,tetrakis(triphenylphosphine)-palladium,and N,N-dimethyl-2-(piperazin-1-yl)benzamide oxalate.LNU-40 possesses a specific surface area of 32 m2/g and manifests thermal stability.Dissolution or decomposition does not occur when it is dispersed in commonly encountered organic solvents.LNU-40 is characterized by a low surface energy and a water contact angle of 152.4°,demonstrating excellent resistance to acidic and alkaline environments.This property enables the fabrication of a superhydrophobic surface with outstanding self-cleaning capabilities.The superhydrophobic flexible fabric prepared with LNU-40 achieves a separation efficiency of over 90%for organic solvents and exhibits an oil adsorption capacity ranging from 3 to 8 times of its own mass.The superior adsorption and separation performance make it suitable for the treatment of oily wastewater containing organic solvents in industries such as petrochemicals,food,and pharmaceuticals.
