Abstract
Tubes by fibre templates (TUFT) is a process that is used
to fabricate tubular materials. Tube dimension depend on
the template fibre size and coating thickness, while tube
regularity depend on the coating and template removal
methods. We have studied preparation of tubes using
electrospun fibres of polyvinyl alcohol (PVA), polyvinyl
pyrrolidone (PVP) and polyamide-66 (PA) as templates,
atomic layer deposition (ALD) of Al2O3 as coating, and
dissolution as well as the heat treatment in template
removal. Smooth tubes were obtained is dissolution of PVP
and PA templates and when heat treatment was used as
template removal. Dissolution of PVA, on the other hand,
produced novel nanostructured and high surface area
coral-like material. This material, which we have called
"nano-coral", has a relatively high surface area due to
the interconnected cavities formed after the removal of
the template. Nanotubular materials has potential in
catalysts carriers, filtration and other application
