| titleOfInvention | A kind of preparation method of cellulose aerogel-based high-efficiency air filtration membrane |
| abstract | The invention discloses a preparation method of a cellulose aerogel-based high-efficiency air filtration membrane, belonging to the field of air filtration materials; Disperse in the mixed liquid of water to obtain cellulose dispersions of different concentrations, pour them into molds for molding, and obtain microbial cellulose aerogel-based high-efficiency air filtration membranes with different thicknesses by freeze-drying; the microstructure of the air filtration membrane is The three-dimensional nano-network composed of microbial cellulose nanofibers has a film-like macroscopic shape, and the film forming process is a physical process, without chemical reaction, and is green and convenient; the air filtration membrane with a thickness of 1-5mm obtained by this method is in the air high The filtration efficiency of removing PM0.3 under the flow rate is high, up to more than 99.9%, and the air resistance is less than 250Pa, the preparation process is simple, and it is beneficial to large-scale production. |
