Pani Layer

Aligned poly (vinylidene fluoride) (PVDF) nanofibers and the nanoropes have been fabricated via a novel electrospinning technique. And then conducting polyaniline (PANI) was coated on the surfaces of the nanoropes using an in situ chemical oxidative polymerization method. It is found that the conductivity increased drastically at first and then tended to be saturation in the polymerization process. In addition, the flexibility and stretchability of the composites have been measured: With an increase of bending curvature and tensile strain, the conductivity rose at the beginning because the fibers among the nanoropes get tight; and then the conductivity dropped, which may due to the PANI layer broke and becomes discontinuous with the adding stress.

Conductive Film

In this paper，ZnO/PANI transparent conductive film has been prepared by in situ chemical oxidative polymerization, APS as an oxidant. The conductivity and transmittance of ZnO/PANI was measured. It has been investigated of the effects of reaction conditions and the doping component on conductivity, transmissivity and adhesion. With the increase of doping ZnO, the conductivity of ZnO/PANI transparent conductive film, transmittance and adhesion reduced. The optimal conditions is that the concentration of An, APS and PVA are 0.75 mol / L, 0.8 mol / L and 0.5wt%, respectively.

The present investigation highlights the synthesis of polyaniline (PANI) coated graphene oxide doped with SrTiO3 nanocube nanocomposites through facile in-situ oxidative polymerization method for the efficient removal of carcinogenic dyes, namely, the cationic dye methylene blue (MB) and the anionic dye methyl orange (MO). The synthesised nanocomposites were characterised by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The adsorption efficiencies of graphene oxide (GO), PANI homopolymer and SrTiO3 nanocubes-doped nanocomposites were assessed by monitoring the adsorption of methylene blue and methyl orange dyes from aqueous solution. The adsorption efficiency of nanocomposites doped with SrTiO3 nanocubes were found to be of higher magnitude as compared with undoped nanocomposite. Moreover, the nanocomposite with 2 wt% SrTiO3 with respect to graphene oxide demonstrated excellent adsorption behaviour with 99% and 91% removal of MB and MO respectively, in a very short duration of time.

This study describes the preparation of polypyrrole multiwall carbon nanotube (PPy/MWNT) composites by in situ chemical oxidative polymerization. Various ratios of functionalized MWNTs are dispersed in the water, and PPy are then synthesized via in-situ chemical oxidative polymerization on the surface of the carbon nanotubes. The morphology of the resulting complex nanotubes (MWNT-PPY) was characterized by field-emission scanning electron microscopy (FESEM). The conductivity of each composite showed a maximum in the temperature scale of 120 – 160 °C and then decreased dramatically with the increase of temperature. The resultant PPy/MWNT nanotubes enhanced electrical conductivity and thermal stability of nanocomposite compared to PPy which was strongly influenced by the feed ratio of pyrrole to MWNTs.
