| titleOfInvention | Preparation method for porous material based on water-in-oil type high internal phase emulsion with stable polymer nanoparticles |
| abstract | The invention discloses a method for preparing an ultralow-density polymer porous material in freezing and drying ways by taking a water-in-oil type high internal phase emulsion with stable styrene, acrylic acid and methyl methacrylate triblock copolymer nanoparticles as a precursor. The method comprises the steps as follows: adding an electrolyte into a water dispersion solution of the styrene, acrylic acid and methyl methacrylate triblock copolymer nanoparticles, after the electrolyte is dissolved by stirring, taking the electrolyte as a water phase, slowly pouring the water phase into an oil phase, magnetically stirring to form the water-in-oil type high internal phase emulsion, standing for a period of time at a room temperature, freezing and drying to form the low-density polymer porous material. The preparation method is simple and easy to implement, and environment-friendly; and the ultralow-density polymer porous material containing no emulsifier can be obtained, and has a density ranging from 0.027g/cm<3> to 0.10g/cm<3> and a pore diameter ranging from 20 microns to 200 microns. |
