摘要：

We report here an in situ polymerization method for the controlled synthesis of core-shell structured hydrogen titanate-polyaniline composite nanowires. The microstructure and physical properties of the composite nanowires were characterized with XRD, FESEM, TEM, FT-IR, thermal analysis, and UV-vis spectroscopy. It is found that the thermal stability of polyaniline in the composite is greatly improved. A hydrogen bond-assisted formation mechanism is proposed to account for the experimental observation. In addition, the temperature dependence of electrical conductivity of an individual composite nanowire was measured as a function of temperature, which reveals improved conductivity compared with hydrogen titanate nanobelt.
