| Abstract Scope |
Flexible and transparent microelectronic components, with functional properties like ferroelectricity, are gaining interest in nowadays research due to their wide application ranges. Here, dielectric BaTiO3 nanoparticles are a good starting material for the fabrication of such. Using electrospinning, nanostructured polymer-oxide composite fibers with great flexibility can be achieved.Targeting at such 1-dimensional BaTiO3 composites, BaTiO3 nanoparticles were formulated for electrospinning. Instead of observing polymer-oxide nanofibers with evenly distributed nanoparticles, the fibers contained large and well-defined micrometer sized needle- and rod-shaped structures. Experiments using electron microscopy and X-ray diffraction revealed that these materials transformations originate from a high reactivity of the BaTiO3 nanoparticles towards water.The influence of different materials properties like particle size, surface area, and crystallinity will be discussed. Not only are those findings important to understand and control the synthesis and processing of such materials, but it also opens possibilities to capture and store CO2. |
