Problems solved by technology

Traditional photocatalysts mainly include nanomaterials, such as nano-titanium dioxide; however, the use of these photocatalyst nanomaterials to treat sewage has been limited to laboratory scientific research for many years, because nanoscale materials with high activity are easy to agglomerate and difficult to recycle, so it is necessary to Load it on the carrier for application
However, its loading technology has encountered a bottleneck that is difficult to break through: the use of inorganic carriers reduces its activity, while organic carriers are easily corroded by light during use.

Abstract

The invention provides a functional nano-composite material, which comprises a flexible fiber carrier and a plurality of functional nanoparticles immobilized in the flexible fiber carrier. The flexible fiber carrier comprises at least one brush-like structure, and the plurality of functional nanoparticles are clamped and fixed in the at least one brush-like structure. The invention also provides a preparation method and application of the functional nano-composite material. In the invention, flexible fiber is adopted as the carrier to realize effective loading of the functional nanoparticles. The loading compounding mode can realize high capacity loading of the functional nanoparticles, and the loading rate is up to 10% of the weight of the flexible fiber carrier. At the same time, the functional nanoparticles can be extended to all scenes in which the flexible fiber carrier can be applied, can be applied to sewage purification, air purification, bacteria resistance, disinfection and other environmental protection fields, and the application range is very wide.

Description

technical field [0001] The invention belongs to the field of nanomaterials, in particular to a nanocomposite material and its preparation method and application. Background technique [0002] At present, the traditional water pollution treatment methods used in the domestic and foreign markets are physical methods, chemical methods, and biological methods, each of which has its own disadvantages, high cost, high energy consumption, and even secondary pollution, and the purely purified water is still " Dead body", only the ecological system that restores the balance of the water body can make the water environment truly "resurrected". Traditional treatment methods cannot fundamentally solve water quality problems. Even if a lot of manpower, material resources, and financial resources are invested, the effect is still very small. Therefore, breakthrough technologies that can completely solve river water pollution control are urgently needed. [0003] Photocatalytic materials ...
