PVPy/MWNTs纳米复合材料的制备及其导电性能研究
Preparation and Electrical Properties of PVPy/MWNTs Nanocomposites
摘要
Abstract
Conducting poly(3-valerylpyrrole) (PVPy)/multi-wall carbon nanotubes (MWNTs) nano-composites have been prepared by in-situ polymerization of 3-valerylpyrrole (VPy) on MWNTs. The structure and properties of the resulting samples are studied by FT-IR, 1 H NMR, XRD, SEM, TEM and TGA. FT-IR, SEM and TEM indicate that no chemical reaction occurred between PVPy and MWNTs, and only the MWNTs serve as a template for VPy polymerization. PVPy is only coated on the external surface of MWNTs and the thickness of the PVPy coating on each nanotube depends on the feed ratio of VPy to MWNTs. XRD patterns of the nanocomposites are investigated, it is clear that the intensity of the peaks at around 25. 82?and 43. 10?decreases with the increase of the mass ratio of VPy to MWNTs. Furthermore, the electrical conductivity of the samples is measured at room temperature, and the results exhibit that MWNTs can enhance the conductivity of PVPy/MWNTs nanocomposites compared to PVPy. The conductivity of PVPy/MWNTs nanocomposites is 1. 42S/cm (VPy/MWNTs = 2. 5/1) and 0. 22S/cm (VPy/MWNTs=5/l), respectively.关键词
