Summary
The authors propose a simple new route to produce oxide nanopowders that are highly enriched with carbon nanotubes (CNTs), and demonstrate it for titania (TiO₂). The method has three stages: first, polymer nanofibres carrying the oxide precursor are electrospun directly onto mats of carbon nanotubes; next, the composite undergoes a thermo-mechanical treatment that improves the interfacial contact between the as-spun fibres and the carbon support; finally, calcination in air converts the precursor into the desired crystalline oxide. This yields titania powders with very high CNT content. The approach is presented as general — in principle it can be extended to any oxide that can be obtained through the electrospinning route.
