Template synthesis method of preparing copper nanotubes via electroless plating has been investigated in this paper. The tubular structures were obtained by calcinring copper-coated carbon nanofibers. The final products were characterized by scanning electron microscopy (SEM), transmission electron microscope (TEM), and x-ray diffractometer (XRD). The results show that copper nanotubes can be synthesized by this method. The inner diameter of the prepared copper nanotubes is about 100 nm, and the wall thickness is about 25 nm. In this method, it is convenient to control the dimension or the shape of the obtained copper nanotubes by using different nanofibers as templates. [ABSTRACT FROM AUTHOR]

Interconnected polyaniline nanofibers with diameters in the range of 30–60 nm and lengths up to several micrometers have been synthesized by chemical oxidative polymerization of aniline in catanionic solution by mixing cetyltrimethylammonium bromide and sodium dodecylbenzenesulfonate. The product was characterized by field‐emission scanning electron microscopy, transmission electron microscopy, UV‐vis spectroscopy, and Fourier transform infrared spectroscopy. The effects of the molar fraction of cetyltrimethylammonium bromide on the morphologies of polyaniline have been investigated. [ABSTRACT FROM AUTHOR]

Continuous and uniform Ni-Co-B coatings were successfully deposited onto carbon nanofibers via electroless plating. SEM images of the prepared Ni-Co-B coated carbon nanofibers were presented. The magnetic properties of the coated carbon nanofibers were investigated. The CoSO4/(CoSO4+NiSO4) ratio in the electroless bath has obvious influence on the coercivity and residual magnetic flux density of the Ni-Co-B coated carbon nanofibers. [ABSTRACT FROM AUTHOR]
