Abstract

The invention discloses a method for preparing a flexible air purification material, belonging to the field of preparation of air purification materials. Aiming at the defects that the desorption is saturated and the pollutants cannot be regenerated and use in the conventional method for removing indoor air pollutants, a method for preparing the flexible air purification material with excellent endurance quality and photo-oxidative degradation resistance is provided. The method comprises the following steps: preparing nanometer Fe-TiO2-La suspension, loading the suspension on a fiber fabric, thereby obtaining the flexible air purification material. The flexible air purification material prepared by the preparation method can eliminate indoor formaldehyde and other poisonous gases under the effect of visible light and achieve an effect of purifying indoor air; and moreover, the flexible air purification material can protect ultraviolet radiation and protect the safety of indoor people and objects, can be repeatedly used, is high in endurance quality and photo-oxidative degradation resistance and has wide application prospects.

Description

Technical field [0001] The invention belongs to the field of air purification material preparation. Background technique [0002] Reports of indoor polluted air harming human health are not uncommon. Therefore, the treatment of indoor air pollution, especially the removal of organic pollutants in indoor air, has become a research hotspot for scientific and technological workers at home and abroad. At present, the main methods for removing indoor air pollutants are: physical adsorption, chemical neutralization, and biological methods. However, the above methods have defects such as saturation of adsorption, complicated manufacturing, high cost, and inability to be regenerated. Summary of the invention [0003] The purpose of the present invention is to provide a method for preparing a flexible air purification material with excellent durability and resistance to photooxidation degradation. [0004] The present invention is realized through the following technical solutions: a meth...
