Method of preparing polyvinylidene fluoride ultra-filtering membrane through extraction of nano cellulose from straw |
| abstract |
The invention discloses a method of preparing a polyvinylidene fluoride ultra-filtering membrane through extraction of nano cellulose from straw and belongs to the field of ultra-filtering membranes. The method comprises the following steps: extracting the nano cellulose from wheat straw; adding the nano cellulose to a chitosan solution with mixing to prepare a suspension liquid; mixing the suspension liquid with a polyvinylidene fluoride membrane-casting liquid; and performing defoaming, membrane scraping and air-drying membrane forming. The polyvinylidene fluoride membrane is improved in hydrophilic performance by means of large specific surface area of the nano cellulose, so that the polyvinylidene fluoride membrane is improved in anti-pollution capability, and is high in water permeability, chemical stability and hydrophilia. |
