Description

technical field

[0001] The invention belongs to the field of materials and environmental protection, and more specifically relates to a plant polysaccharide airgel air purification material, and also relates to a preparation method of the plant polysaccharide airgel air purification material. Background technique

[0002] The rapid development of modern social economy has caused the pollution and deterioration of the air environment, and some new materials are urgently needed to solve these problems. The emergence and application of airgel materials provide a solution to air pollution. Compared with traditional technologies, airgel adsorbents have many advantages, such as little or no adsorption loss, low waste disposal costs, and high efficiency. and reuse etc. Aerogel, also known as xerogel, is a highly dispersed solid material with a nanoporous network structure composed of colloidal particles or polymer molecules, and filled with gaseous dispersion media in the pores. ...
