Abstract

The invention discloses a transparent PM2.5 filter membrane with photocatalysis and a preparation method thereof. The PM2.5 filter membrane is a composite nanofiber membrane with a sandwich-like structure, including polyacrylonitrile@TiO 2 and polyamide-6, the nanofiber diameter distribution of the composite nanofiber membrane is 60 to 100nm. The composite membrane is tightly cross-linked and has photocatalytic function, high transparency and efficient PM2.5 filtration performance. When used in anti-nano screen windows, it can not only effectively block outdoor PM2.5 from entering the room, but also effectively prevent outdoor PM2.5 from entering the room under the influence of sunlight. Photocatalyzes low-concentration harmful gases in the atmosphere while maintaining good lighting and ventilation effects.

Description

technical field

[0001] The invention belongs to the technical field of filter material preparation, in particular to a photocatalytic transparent PM2.5 high-efficiency filter membrane and a preparation method thereof. Background technique

[0002] With the development of industrialization, the pollution of the environment and air has further intensified, and the harm caused by PM2.5 has attracted worldwide attention. PM2.5 is called "particulate matter that can enter the lungs", which can directly enter the lungs of people. Because it contains toxic and harmful substances, stays in the air for a long time, and is transported over a long distance, it will inevitably affect the quality of the air environment and human health. Negative impact. In addition, the indoor air quality has also attracted people's attention, especially during severe smog, the PM2.5 value in the indoor air is even higher than that in the outdoor air, and at the same time, the indoor VOCs concentration ...
