Fabrication of porous polymer spheres through solvent extraction |
| 초록 |
Porous polymer particles have attracted great interests due to numerous applications in many areas of advanced materials science. This research introduces preparation of the porous polymeric particles by γ-ray radiation and solvent extraction. The sodium poly(styrene sulfonate) emulsions are formed in the hexadecane with surfactant. We chose the inverse emulsion polymerization format with surfactant to form water in oil (w/o) emulsions. So, polymeric particles have been fabricated by γ-ray induced crosslinking of polystyrene sulfonate and the pores are formed by MEK which extracts the water within the polymer particles because MEK is miscible in both organic solvents and water. The size and the morphology of the synthesized particles have been characterized by dynamic light scattering (DLS) and scanning electron microscope (SEM). |
