| titleOfInvention | A kind of degradable biological base air filter film and preparation method thereof |
| abstract | The invention belongs to technical field of air purification, specifically provides a kind of degradable high-efficiency air filtering fiber film material of bio-based.This air filtration tunica fibrosa is using biological based high molecular soybean protein and polyvinyl alcohol as material of main part, and it is prepared with the one or more in the water-soluble natural polymeric derivative such as methylcellulose, chitosan, hydroxyethyl cellulose for auxiliary material by method of electrostatic spinning.Wherein a diameter of 100 1000nm of nanofiber, fiber film thickness are 20um 100um, and porosity can reach more than 65%, and pore size is 10 100nm, and filter efficiency can reach more than 90%.The degradable air-filtering membrane of the bio-based is processed to can be used for the multiple uses such as mouth mask, screen window, air purifier, and securely and reliably, cost is low.Meanwhile preparation method is simple, not high to equipment requirement, production cost is low, obtained air-filtering membrane good purification, strong adsorption force, degradable recovery, has good market prospects. |
