| titleOfInvention | Waterborne polyurethane/Fe3+Preparation method of gel material |
| abstract | The invention relates to waterborne polyurethane/Fe 3+ A preparation method of the gel material. The invention aims to solve the problems of poor mechanical tensile property, long self-repairing time consumption and the like of the existing hydrogel, and the technical scheme is as follows in order to achieve the aim: firstly, adding an end-capping agent containing sulfydryl into PPU to obtain a sulfydryl-end polyurethane prepolymer, then dispersing a dopamine methacrylamide monomer, adding the dopamine methacrylamide monomer into the prepolymer, then adding a photoinitiator, reacting under the irradiation of an ultraviolet lamp, neutralizing and emulsifying a reaction product to obtain a catechol-group-containing waterborne polyurethane emulsion, and finally, adding the prepared emulsion and FeCl 3 The solutions are mixed according to a certain proportion, and the pH value is regulated to obtain gel materials with different colors. The prepared gel material is sensitive to PH change and has good self-repairing capability and tensile strain performance. |
