长链烷基修饰的疏水共价有机框架的合成及油水分离性能
Synthesis of hydrophobicity covalent organic framework modified by long-chain alkyl and its performance of oil-water separation
摘要
Abstract
Covalent Organic Frameworks(COFs)are a class of organic porous materials that have been widely used in the field of adsorption and separation due to their ordered pore structures,large specific surface areas,and tunability.By introducing hydrophobic long-chain alkyl groups into the phenanthroimidazole structural units,a superhydrophobic-superoleophilic COFs material(TFPB-PIP-C12 COF)was synthesized"from bottom to top"through the solvothermal method.The structure of the synthesized TFPB-PIP-C12 COF material was characterized and confirmed using Fourier-transform infrared spectroscopy(FT-IR),powder X-ray diffraction(PXRD),scanning electron microscopy(SEM),and transmission electron microscopy(TEM).The results of contact angle and oil-water separation tests showed that the material exhibited superhydrophobicity(water contact angle of 133.2°)and could efficiently separate five kinds of oil-water mixtures.Especially,the separation efficiency for chloroform reached 99%,and the flux was 11 854.2 L·m-2·h-1.This method enriched the structural diversity of COFs,enhanced their application potential in the field of oil-water separation,and had high practical application value.关键词
