| titleOfInvention | A kind of protein nanocellulose composite multifunctional separation membrane, preparation method and application thereof |
| abstract | The invention discloses a protein nanocellulose composite multifunctional separation membrane, a preparation method and an application thereof. This method is based on the immobilization of amyloid oligomers (positively charged) obtained by natural lysozyme reduction of disulfide bonds on the surface of TEMPO oxidized cellulose fibers (TOCNs) (negatively charged) via electrostatic interactions and hydrogen bonds. , and then a composite film is obtained by film forming. The lysozyme oligomer acts as an adhesive to attach to the TOCN surface, providing a variety of functional groups, which can interact with pollutants in water or toxins in the human body, and make the TOCN bond more tightly to reduce lysozyme/TEMPO oxidation fibers The pore size to cut-off size of the plain nanofiber composite membrane is 3 nm. The composite membrane can remove heavy metal ions, bilirubin, oil droplets, and even effectively enhance the removal ability of boron. The present invention provides a fast, environment-friendly and economical membrane-making scheme by using biomass as a raw material, and the separation membrane has great application prospects in the purification of wastewater and the removal of toxins from the human body. |
