With the development of cities, air pollution is becoming more serious, and with the prevalence of epidemic diseases, substances which are invasive to human bodies, such as dust, pollen, bacteria and the like, are diffused in the air. In order to take appropriate preventive measures, the demand for masks is increasing in daily life. However, the filtering efficiency of the general commercial masks is not sufficient at all to cope with various harmful substances in the air.

The scientific and technological development is thousands of days, and various advanced nano materials come out in succession and become new material pets in the filter material market. Different nano materials are mixed with the base material, so that the optimized filter material with various functions can be manufactured, including ultraviolet resistance, antibiosis, adsorbability enhancement, dust holding capacity and the like, so that the defense capability to different harmful substances in the air is improved. However, different materials have different physical and chemical properties, and are inevitably repulsive when mixed with a base material, so that the compounding difficulty is increased. In order to make the materials easier to combine, the filter material is preferably combined with a single nano material to form a novel filter element, such as a graphene composite filter element, a nano zinc oxide filter element, a nano silver filter element and the like. In contrast, it is rare to use multiple nanomaterials for compounding and compounding. Therefore, the new filter element is formed by combining two famous reinforcing materials, namely nano zinc oxide and graphene, and a polymer base material by a process different from the prior art, so that the adsorption and dust holding capacity of the mask are enhanced, and an automatic sterilization mechanism is provided.

Graphene is a very excellent filter material, has a unique structure and physicochemical properties, and can effectively adsorb a large amount of pollutants including PM2.5 micro dust harmful to a human body, so as to improve the purification function of water and air; the nano zinc oxide is an effective bactericide, has three different sterilization mechanisms, namely zinc ion release, photocatalytic antibacterial and active oxygen antibacterial, and can autonomously eliminate surrounding microorganisms. Therefore, the novel mask filter material compounded by the two nano materials and the polymer is superior to a common mask, has higher filtering efficiency and can independently sterilize.
