Abstract

In this paper, we report synthesis and characterization of flexible polymer-derived ceramic silicon carbon nitride nanotubes decorated with barium titanate (BTO) nanoparticles where multi-walled carbon nanotubes act as a template. The synthesis was achieved by controlled pyrolysis of polyurea (methylvinyl) silazane and BTO metal-organic precursor. Structural characterization by advanced microscopy techniques revealed 10-50 nm BTO nanoparticles uniformally covering the nanotubes. X-ray photoelectron spectroscopy was used to confirm the BTO perovksite phase. Possible application of this novel structurenanoNecklaceis in nanocapacitors (NCs) where high dielectric material BTO is arranged on SiCN layer.
