Synthesis of porous PS/PMMA microspheres through pickering emulsion and γ-ray radiation |
| 초록 |
Porous microspheres possess competitive advantages such as high specific surface area and low density. This research shows fabrication of porous SPS/PMMA(Sulfonated polystyrene/Poly methyl methacrylate) microspheres using γ-ray radiation and pickering emulsion. Porous SPS/PMMA microspheres has different pore sizes. The PS(Polystyrene) particles were located at interface between water and monomer. They can form pickering emulsions by shear force. Then, monomer will be absorbed into particles because of swelling properties of PS particles and water also diffuse into the particles by osmosis. These two factors induce the pores on the particles. They show different pore sizes and morphology depending on sulfonation time and swelling time. As the sulfonation time increases 2h to 18h, hydrodynamic diameters increased 2.51㎛ to 3.65㎛ and the particle size increased 4㎛ to 10~15㎛ and the pore size increased 1㎛ to 2㎛. |
