Influence of inclusion of sulfonate (-SO3-) on surface sealing of polystyrene (PS)-based bowl |
| 초록 |
In this study, we seal thermal annealing-driven surface of polymer hollow particles with a different surface property. Use of phase separation between polystyrene (PS) solid particles incorporated with sulfonate (-SO3-) group and decane allows their transformation into hollow particles with an opening on the surface. Control of the phase separation enables us to tune the hollow particle's structure like outer and inner diameters and size of the opening. structural change of the hollow particles is experimentally observed and theoretically analyzed while thermally annealed at a temperature above Tg of the polymer. The results show that the change in the surface property of the hollow particles due to the incorporation of the -SO3- group can have a direct impact on their sealing behavior and surface-sealed structure. |
