Embodiment 1

[0024] With 0.38g (1.5mmol) copper methacrylate, 0.16g (1.5mmol) styrene, 0.01g (amount: 2% of the total mass of the polymer) azobisisobutyronitrile and 25mL (0.3mol) N, N-dimethylformamide was added into a 50 mL three-necked flask, stirred at room temperature for 60 min, and then placed in an oil bath at 70° C. for 4 hours. After the reaction was stopped, it was left to stand and filtered to obtain a polymer containing copper methacrylate.

Embodiment 2

[0026] The polymer obtained from the reaction in Example 1, 0.11 g (0.5 mmol) of trimesic acid and 25 mL (0.6 mol) of methanol were added into a 50 mL reactor and reacted for 24 hours at room temperature. After the reaction stopped, it was left to stand for crystallization, filtered and dried to obtain the copolymer / HKUST-1 hybrid material.

Abstract

The invention discloses a method for preparing a copolymer/HKUST-1 hybrid material by in-situ polymerization and belongs to the technical field of skeleton materials. Specifically, the invention relates to a classical porous metal-organic skeleton material prepared from trimesic acid as an organic ligand, a copper methacrylate monomer for providing metal ions and a styrene monomer through polymerization and coordination chemistry self-assembling at the normal temperature. The method improves the stability of HKUST-1. The copolymer/HKUST-1 hybrid material combines functions of a polymer and anorganic skeleton material and has wide application values. The produced HKUST-1 and the polymer are bonded through a covalent bond so that the agglomeration of a large amount of MOF particles is avoided and the MOF is uniformly dispersed in the copolymer. The hybrid material realizes the integration of functions of the metal-organic skeleton HKUST-1 and the polymer.

Description

technical field [0001] The invention belongs to the preparation technology of a metal-organic framework and a polymer hybrid material by a new method, and belongs to the technical field of framework materials. Background technique [0002] Metal-organic frameworks (MOFs) are a new class of porous crystalline materials based on self-assembly of organic ligands and metal ions. Metal ions or metal clusters act as nodes, and organic ligands act as bridges, often forming long-range ordered crystalline materials with regular channels. Compared with traditional porous materials, it has many advantages such as adjustable pore size, large specific surface area, diversified skeleton components, and adjustable pore modification. In view of the above advantages, metal-organic framework materials have important application prospects in the fields of gas adsorption and separation, light, electricity, magnetism, sensing, and catalysis.
