Abstract

The invention provides a Cu-BTC-based load type biological fiber multifunctional composite material which has excellent catalytic decomposition performance for a chemical toxic agent and a preparation method of the composite material and belongs to the technical field of functional materials. The material is formed in the mode that the biological fiber surface is loaded with a metal organic framework compound Cu-BTC through covalent bonds. The preparation method includes the steps that biological fibers are immersed in a biological fiber solution for carboxymethylated processing, and then residual liquid which does not react is flushed and removed with distilled water; the biological fibers which are subjected to carboxymethylated processing and washed to be clean are soaked in a Cu(OAc)2 absolute ethyl alcohol solution and a 1, 3, 5-benzene tricarbonic acid absolute ethyl alcohol solution, and the Cu-BTC-based load type biological fiber multifunctional composite material is obtained. The composite material is simple in preparation method and good in biocompatibility, has the functions of stopping bleeding and promoting healing of wounds, hygroscopicity and an antibacterial property and is high in digestion rate of chemical toxic agent and capable of being recycled. The novel multifunctional composite material can serve as medical sterile dressing for treating and curing wounded persons infected by the chemical toxic agent and a breathable multifunctional protection material which can discharge sweat and effectively discompose the chemical toxic agent and used for military equipment.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a Cu-BTC-based load type with excellent catalytic and digestion properties for chemical poisons at room temperature, hemostasis, wound healing promotion, good hygroscopicity and antibacterial properties, and biodegradability Multifunctional fiber composite material and its preparation method and use. Background technique [0002] With the growth of international terrorist activities and the proliferation of nuclear, biological and chemical weapons technology, the threat of nuclear, biological and chemical terrorist activities is on the rise worldwide. The severe situation of chemical weapons in neighboring countries makes our country still in the severe threat of chemical weapons. And with the development of modern chemical technology and the proliferation of chemical weapons production technology, chemical terror has intensified. Chemical weapons armam...
