| Abstract: | Polystyrene (PSt)/poly (4-butyltriphenylamine; PBTPA) composite particles was prepared by a chemical oxidative seeded dispersion
polymerization of (4-butyltriphenylamine) with PSt seed particles that were prepared by nonaqueous dispersion polymerization
of styrene. Monodisperse composite particles were obtained when the ratio of monomer to seed, the rate of monomer feed, and
poly(N-vinyl pyrrolidone; PVP) concentration was appropriately selected. The introduction of PBTPA was confirmed by the presence
of the characteristic absorption band attributed to PBTPA from a Fourier transform infrared spectra. The solvent extraction
with ethyl acetate revealed that composite particles consisted of PSt core and PBTPA shell. Then two-dimensional arrays of
composite particles were also fabricated. |
