| titleOfInvention | Polyurethane hydrophilic modification method based on polystyrene diazonium salt |
| abstract | The invention relates to a polyurethane hydrophilic modification method based on polystyrene diazonium salt. The invention relates to a polyurethane hydrophilic modification method based on polystyrene diazonium salt, which comprises the following steps: step 1: weighing a proper amount of polystyrene diazonium salt solution, and soaking a polyurethane carrier in the polystyrene diazonium salt solution for a certain time under a certain temperature condition; step 2: and after soaking, taking out the polyurethane carrier, cleaning with water, blowing with cold air for a certain time, soaking the polyurethane carrier in a solution of anionic polyelectrolyte, adsorbing and soaking for a certain time under the condition of a certain temperature, taking out and drying, and thus completing the hydrophilic modification process of the polyurethane carrier. The invention utilizes the property of polyfunctional group and high reaction activity of the polystyrene diazonium salt to fix the anionic polyelectrolyte on the surface of the polyurethane to realize hydrophilic modification of the polyurethane. |
