Embodiment 1

[0040] (1) Under inert gas atmosphere, dissolve 0.04mol Boc-D-phenylalanine and 0.04mol cholesterol in chloroform, then dissolve 0.04mol DCC and 0.004mol DMAP in 10mL dichloromethane, add dropwise The reaction system was reacted under ice bath conditions for 4 h and then reacted at room temperature for 20 h. The crude product cholesterol amino acid ester derivative 1 was obtained after the reaction solution was processed. Further, tetrahydrofuran: n-hexane=1:6 (v / v) was used as the mobile phase, and the reaction was carried out through The crude product was purified by column chromatography to obtain pure cholesterol amino acid ester derivative 1; the above cholesterol amino acid ester derivative 1 formed hydrochloride under the action of HCl, and then refluxed in benzene at 80 ° C for 4 hours to obtain cholesterol amino acid ester primary amine 1; Dissolve the obtained primary amine 1 of cholesterol amino acid ester in chloroform, then add a solution of furanaldehyde in chloro...

Embodiment 2

[0050] The imine bond-containing cholesterol derivative 1 obtained in Example 1 was added to a 4 mL sample bottle as a stabilizer, 0.015 mL of pyrrole and 500 mL of benzene were added, shaken and mixed evenly, and then 500 mL of FeCl was added. 3 The aqueous solution was fully mixed with a mixer, and after standing for a period of time, polypyrrole gel emulsion 2 was obtained.

[0051] The obtained polypyrrole gel emulsion 2 is polymerized, washed and dried to obtain a polypyrrole porous material 2 . Other steps are the same as in Example 1.

Embodiment 3

[0053] The imine bond-containing cholesterol derivative 1 obtained in Example 1 was added to a 4 mL sample bottle as a stabilizer, 0.043 mL of pyrrole and 300 mL of benzene were added, shaken and mixed evenly, and then 700 mL of FeCl was added. 3 The aqueous solution was fully mixed with a mixer, and after standing for a period of time, polypyrrole gel emulsion 3 was obtained.

[0054] The obtained polypyrrole gel emulsion 3 is polymerized, washed and dried to obtain a polypyrrole porous material 3 . Other steps are the same as in Example 1.

Abstract

The invention discloses a hydrophobic polypyrrole porous material as well as a preparation method and application thereof, and belongs to the field of material preparation. According to the preparation method of the hydrophobic polypyrrole porous material disclosed by the invention, the hydrophobic polypyrrole porous material is prepared by taking a synthesized small-molecule gelatinizing agent containing an imine bond as a stabilizer and a gel emulsion as a template, and the pore structure of a polypyrrole block and the size under the microstructure can be regulated and controlled according to the difference of the oil-water ratio and the pyrrole content; the polypyrrole porous material has the characteristics of porosity and hydrophobicity, so that the polypyrrole porous material can be used for adsorption of organic solvents; and the method is mild in reaction condition, simple in synthesis process, low in energy consumption, simple in post-treatment and green. The method solves the problems of high energy consumption in the preparation process of the porous material and incapability of large-scale preparation of the polypyrrole material.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to a hydrophobic polypyrrole porous material, a preparation method and applications thereof. Background technique [0002] In recent decades, with the acceleration of industrialization, the treatment of organic pollutants, especially oil spills, has attracted more and more attention. However, dealing with these pollutants in an efficient and practical way presents an imminent challenge for scientists working in this field. At present, the most effective method to remove pollutants from water is selective adsorption separation. [0003] Porous materials have attracted extensive attention due to their low density, high specific surface area, good permeability, and excellent adsorption. The preparation of porous materials mainly focuses on controlling the pore size, shape, distribution, and how to introduce functional groups into the materials to impart specific functionality. Th...
