| titleOfInvention | Emulsion solvent volatilization method for preparing macroporous polymer microspheres |
| abstract | The invention belongs to the technical field of high molecular materials, and particularly relates to a method for preparing macroporous polymer microspheres by an emulsion solvent volatilization method. The method takes ethyl cellulose and polyacrylic resin IV as polymer raw materials, utilizes the hydrophilic and hydrophobic properties of the components and the pH response characteristic of the polyacrylic resin IV, and combines an emulsion solvent volatilization method to obtain the macroporous polymer microspheres with uniform particle size and high porosity. The invention regulates and controls the pore structure of the polymer microsphere by regulating the pH value of the system, and the preparation process is operated at room temperature, thus being simple and easy to operate; meanwhile, the waste of raw materials in the synthesis of the block copolymer is avoided, the resource utilization rate is improved, the whole process can be completed at room temperature, and the energy consumption is saved. |
