Problems solved by technology

However, the currently reported organic conjugated polymers are amorphous, exist in the form of powder, and have the characteristics of insolubility and non-melting, so it is difficult for industrial application
Although it has been reported in the literature that superhydrophobic conjugated polymers can be doped on ordinary sponges to prepare strong hydrophobic sponge adsorption materials, the combination of polymers and sponges is not tight enough and it is easy to fall off.

Embodiment 1

[0034] (1) Synthesis of products

[0035] 1. Synthesis: 3mmol of 1,4-diethynylbenzene, 2mmol of 1,3,5-triethynylbenzene, 150mg of bis(triphenylphosphine)palladium dichloride, 30mg of cuprous iodide, Commercially available sponges were cut into 10mm pieces (120mg) and placed in a dry 100ml round bottom flask. Pass argon gas into the round bottom flask and exhaust the air for 20 minutes to form an anhydrous and oxygen-free environment. Then add 20ml of toluene and 20ml of triethylamine into the device with a syringe, stir vigorously under argon atmosphere, then raise the temperature to 80°C, and react for 8h.

[0036] 2. Filtration: Wash the product with dichloromethane, acetone, deionized water, and methanol, and vacuum-dry it at 70°C for 3 hours to obtain an elastic hydrophobic material with a mass of 220mg. That is to say, 100 mg of the polymer is densely grown inside the 80 mg of sponge, which is difficult to remove.

Abstract

The invention discloses an elastic hydrophobic material, a preparation method thereof and application of the material to removal of organic compounds in water. In particular, after acetylenyl benzene is polymerized in a sponge, a polymer forms a hydrophobic micro-nanostructure inside the sponge, and an elastic highly hydrophobic material is finally formed. The material can selectively adsorb / separate oil or non-polar organic solvents in a water body, simultaneously has better elasticity and can separate the organic compounds by way of extrusion after the adsorbed organic compounds are saturated. The synthetic process of the material is simple, has low requirements for equipment and can achieve industrial scale production. The material has high efficiency of removing organic matters in water, has a simple regeneration process, is low in cost and has extensive application prospects.

Description

technical field [0001] The invention belongs to the field of polymer material synthesis and application, and in particular relates to an elastic hydrophobic material, its preparation method, and the application of the material in removing organic compounds in water. Background technique [0002] Water resources are an important material basis for sustainable economic and social development. However, water pollution caused by industrial organic waste discharge and marine environment pollution caused by oil spills have caused serious ecological disasters to freshwater resources and the marine environment. For example, the petrochemical production process produces high-concentration organic wastewater. Due to the complex composition and high content of organic compounds, it is difficult to biochemically directly, resulting in eutrophication of the water body and the loss of animal and plant species. With the development of the global economy, the amount of crude oil extracted o...
