Abstract:

A general approach of swelling was used to synthesize the TiO2/PS Janus composite particles. The TiO2/PS Janus composite particles were modified at the knob of TiO2 with aniline to synthesize the PANi/PS Janus composite particles. The surface morphology, component and properties of Janus particles were characterized by scanning electron microscope(SEM), energy dispersive spectrometer(EDS), elemental analysis, transmission electron microscope(TEM), Fourier transform infrared spectrometer(FTIR), thermogravimetric analysis(TGA), ultraviolet spectrophotometer(UV) and four-probe measurement. The results showed that the snowman-like PANi/PS composite particles were dark green. The average diameter of the knob of PS was about 228 nm and that of PANi knob increased from 258 nm which was the average diameter of TiO2 knob in TiO2/PS Janus composite particles to 295 nm. Ti elements could not observed by EDS which was replaced by N element. The mass fraction of PANi in PANi/PS Janus composite particles was about 23.7%. Compared with that of the TiO2/PS Janus composite particles, the conductive properties of PANi/PS Janus particles which was redoped by p-toluenesulfonic acid increased obviously and the conductivity was 0.247 S/cm.
