| titleOfInvention | Polyethyleneimine-sodium alginate/silica ultrathin hybrid film and its preparation and application |
| abstract | The invention discloses a polyethyleneimine-sodium alginate/silicon dioxide ultra-thin hybrid film. The thickness of the ultra-thin hybrid film is 80-370nm. Silicon inorganic part composition. Among them, the concentration of sodium silicate is 1-15mmol/L, the pH of the mixture solution of polyethyleneimine and sodium alginate and sodium silicate is 8, and the number of repeated assembly is 2-10. The preparation process includes: hydrolysis of polyacrylonitrile ultrafiltration membrane; preparation of polyethyleneimine solution and sodium alginate sodium silicate solution, and adjusting pH with HCl; alternate assembly of polyethyleneimine solution and sodium alginate sodium silicate solution. The preparation conditions of the ultra-thin hybrid membrane of the present invention are mild and environmentally friendly, and the prepared membrane material is used for dehydration of a pervaporation ethanol/water mixed system, and has better permeation flux and separation factor. |
