Problems solved by technology

This method removes the alkali-soluble metal oxide attached to the surface of the fiber through the sheath-core fiber melt spinning process, and endows a large number of pits on the surface of the gray cloth to improve the adhesion between the metal layer and the surface, but the porous fiber prepared by this method / The fabric only utilizes the micron-scale pits on the surface of the gray fabric, and the physical adhesion is still very limited

Abstract

The invention provides a transition metal porous modified textile adsorbing titanium dioxide and a preparation method thereof. The preparation method of the transition metal porous modified textile adsorbing titanium dioxide includes the steps of mixing and grinding zinc powder and transition metal powder to be then tiled on a template, conducting zinc evaporation by rolling and vacuum heating toobtain a three-dimensional double continuous transition metal porous material, adding titanium precursor to a mixed solvent of ethanol and glacial acetic acid to be uniformly mixed, heated and stirred, performing stirring after adding dropwise ethanol aqueous solution containing hydrochloric acid, adding the three-dimensional double continuous transition metal porous material to continue stirringand aging and obtain titanium dioxide sol modified by the transition metal porous material, and conducting low temperature plasma treatment on a textile base fabric surface which is immersed in the titanium dioxide sol modified by the transition metal porous material to perform two dip and two rolling, and pre-baking to obtain the transition metal porous modified textile adsorbing the titanium dioxide. The transition metal porous modified textile adsorbing titanium dioxide and the preparation method thereof have the advantages of providing functional materials and textiles of strong adhesion,endowing the textiles with such excellent properties as electromagnetic shielding and anti-aging properties.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a textile modified by a transition metal porous material adsorbing titanium dioxide and a preparation method thereof. Background technique [0002] Nanomaterials refer to a mesoscopic level between microscopic structures such as grains and grain boundaries that can reach nanoscale, assembled by limited molecules, and combined macroscopic substances and microscopic atoms and molecules. Porous nanomaterials are materials with regularly or irregularly distributed pores at the nanoscale in the matrix. According to the size of the pores, they can be divided into: microporous materials (pore diameter less than 2nm), mesoporous materials (pore size in 2-50nm) and macroporous materials (pore diameter greater than 50nm), and can be divided into honeycomb materials and foam materials according to the distribution of pores, wherein the holes in the honeycomb material a...
