Abstract

Highly-yielded TiO₂＠SiO₂ submicron-scaled coaxial cables have been successfully synthesized via a static electricity spinning technology. The microstructures and components of the samples were studied by TGA-DTA, XRD, SEM, TEM, EDS and FTIR techniques. The as-prepared sub-micro coaxial cables with a mean diameter of 450 nm and shell thickness of 90 nm had a crystalline TiO₂ core and an amorphous shell of SiO₂. The length of the TiO₂＠SiO₂ cable was longer than 300 μm. Some submicron tubes were also found in the samples, and their formation mechanisms were also discussed in detail.

Key words: static electricity spinning, sub-micro cable, coaxial cable, TiO₂, SiO₂
