【摘要】 |
|
Fibrillar conductive polyaniline/TiO2 (PANI/TiO2) nanocomposites with different TiO2 amount were synthesized with a template-free in situ polymerization method and characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and conductivity measurement. The morphology determination shows that the PANI/ TiO2 composite nanofibers are relatively uniform with the diameter and length in the range of 20?40 nm and 390?420 nm respectively. It also shows that the TiO2 of the composite is rutile crystalline and PANI has some degree of crystallinity. The IR measurement indicates that there is a strong interaction between the PANI and TiO2 nanoparticles, and it has a beneficial effect on the thermal stability of the composite nanofiber. The conductivity of PANI/TiO2 composites changes with TiO2 amount and reaches an optimum value of 2.86 S/cm at 11.1 wt% TiO2. |
