Synthesis of Micron-Size PMMA/Clay Nanocomposite Particles via Multi-Staged Seeded Emulsion Polymerization |
초록 |
Poly(methyl methacrylate)/clay nanocomposite particles with micron size were successfully prepared using multi-stage seeded emulsion polymerization. The content of montmorillonite in the Poly(methyl methacrylate)/clay nanocomposite was decreased as low as 6 wt.% based on the methyl methacrylate monomer. Seed particle size of nanocomposite used in this study was in the range of 275∼300 nm in diameter. Final particle size of nanocomposite was in the range of 1.2 μm in diameter. 2,2-azobis(isobuthylamidine hydrochloride) and n-dodecyl trimethylammonium chloride were used as an initiator and a surfactant in cationic emulsion system. Potassium persulfate and sodium lauryl sulfate were used as an initiator and a surfactant in anionic emulsion system. the evidence of intercalated and/or exfoliated structure of montmorillonite in the nanocomposite prepared in our experiment was confirmed by wide angle x-ray diffraction patterns of d001 plane. Thermal behavior of nanocomposite was traced using DSC and TGA. |
