Abstract
Electrospinning is a method capable for production of
submicron and nanosized fibres in industrial scale. In
electrospinning, the electrostatic field stretches the
polymer solution into fibres at the same time when the
solvent is evaporating. The diameters of formed fibres
are typically in sub-micron range and they can be
collected as interconnected fibrous web onto surface of a
substrate. Submicron fibres composing of suitable
polymeric material can be converted into carbon fibres
having submicron and even nanosized fibre diameters by
stabilization and carbonization processes. The small
fibre diameter, small pore size, and high surface area of
the nanofibre web are properties that are advantageous
for various applications including catalysis.
In this presentation we will review preparation of carbon
fibre sheet material composing of sub-micron sized
fibres. Precursor fibres were prepared from
polyacrylonitrile (PAN) and mixture of PAN and carbon
nanotubes (CNT's). Carbon sheets were prepared using
quasi continuous carbonization process. We will discuss
process-property relationships of precursor production as
well as stabilization and carbonization processes.
Studied properties include e.g. dimensions of the
structure, mechanical properties and electrical
conductivity. Work was carried out within Catapult
project; novel CATAlyst structures employing Pt at Ultra
Low and zero loadings for auTomotive MEAs; Supported by
EU FCH-JU; Grant agreement no 325268.
