| titleOfInvention | Preparation method of organic-inorganic blend membrane |
| abstract | According to the preparation method of the organic-inorganic blend membrane, a polyethylene glycol solution with the solid content of 0.5-1% is added into a polyurethane polymer solution with the mass fraction of 10-18% to obtain a uniformly dispersed polyethylene glycol-polyurethane solution; adding negative oxygen ion powder with solid content of 12-18%; coating on release paper, immersing in water, taking out after the organic-inorganic mixed solution is solidified into a film, cleaning, drying, and soaking the polyurethane-based film in silver nitrate solution to be adsorbed in a dark place; and sequentially adding a disodium hydrogen phosphate solution and hexadecyl trimethyl ammonium bromide into a silver nitrate solution, carrying out a light-resistant reaction, taking out the polyurethane-based film, cleaning and drying to obtain the organic-inorganic blend film. The invention has the following characteristics: 1. the catalytic performance of the catalyst is improved, the specific surface area of the reaction is increased, the reaction active sites are increased, the photo-corrosion is reduced, and the service life of the catalyst is prolonged; 2. the substrate material is safe, nontoxic and environment-friendly. |
