Synthesis of Sulfur-Rich Polymer Nanoparticles through Interfacial Polymerization in Water and Their Surface Modification |
초록 |
Sulfur exhibit an array of desirable properties, but there is a limitation in processing because of low solubility in common solvents. In order to fully exploit the desirable properties of elemental sulfur, methods to obtain high sulfur-content materials in processable forms are crucial. We herein report the synthesis of sulfur-rich polymer nanoparticles from the interfacial polymerization of sodium polysulfide and 1,2,3-trichloropropane in water. Aqueous sodium polysulfide is prepared by dissolving elemental sulfur in sodium sulfide solutions. The treatment of the sodium polysulfide solution with 1,2,3-trichloropropane in the presence of suitable surfactants affords well-defined nanoparticles. The surface of polysulfide nanoparticles could be further functionalized by using end-modified surfactants followed by thermally induced radical addition reaction. The method allows for the preparation of stable polysulfide nanoparticles with positively charged surfaces. |
