Problems solved by technology

On the other hand, in general polymer nanocomposites, the overall catalytic activity of the material decreases due to the leaching of the inorganic catalytic centers during the catalytic process due to their weak interaction with the polymer matrix.

Abstract

The invention belongs to the technical field of composite materials for catalytic degradation of chemical warfare agents, and discloses a polymer zirconium cluster compounded chemical warfare agent catalytic degradation material and a preparation method thereof. The polymer zirconium cluster compounded chemical warfare agent catalytic degradation material is mainly prepared from zirconium clusters and polyethylene glycol monomers; the polyethylene glycol monomer is more than one of polyethylene glycol monomethacrylate and polyethylene glycol monoacrylate; the zirconium cluster comprises Zr and an acrylic acid ligand. The invention also discloses a preparation method of the material. The material is good in mechanical property, high in catalytic efficiency on chemical warfare agents and simulants thereof, good in catalytic stability and easy to recycle, and is colorless and transparent in dry and swelling states. The method is simple.

Description

technical field [0001] The invention belongs to the technical field of composite materials for catalytically degrading chemical warfare agents, and in particular relates to a polymer zirconium cluster composite chemical warfare agent catalytic degradation material and a preparation method thereof. Background technique [0002] Chemical warfare agents (CWAs) mainly include sarin (GB), soman (GD), sulfur mustard (HD) and VX nerve gas. Among the various chemical warfare agents, nerve agents (such as GB, GD, and VX) are the most notorious agents, whose great toxicity comes from irreversible binding to acetylcholinesterase, resulting in a lethal accumulation of acetylcholine (acetylcholine is executed in the body Many functional neurotransmitters) shut down nerve function and breathing, leading to asphyxia within minutes. Nerve agents are a class of organophospholipids, which can be destroyed by hydrolyzing P-X bonds to achieve the purpose of degrading nerve agents. [0003] So...
