Abstract
Electrospinning is a method that can be used in the
production of polymeric nanofibres. Polymer solution is
drawn into sub-µm to nanosized fibres utilizing electric
field. The structure of electrospun web has intrinsic
properties such as small fibre diameter, small pore size,
and high specific surface area which are beneficial for
various applications. In addition, fibres can be
functionalized in various methods. Thin (nm scale),
conformal coatings made by atomic layer deposition (ALD)
can be used for functionalization. For example, metal
oxides can provide interesting properties, such as
electronic, antimicrobial, self-cleaning and hydrophobic
properties among others, to fibrous materials. Combining
electrospinning and thicker ALD layer enables also
preparation of sub-µm tubes, if core fibres are removed.
Aim of this work was to make electrospun fibres from
three polymers, cellulose acetate (CA), polyether
sulphone (PES) and poly-L-lactide (PLLA) to be used as
substrates for ALD. In this presentation we will report
preparation electrospun fibres using solvent mixtures,
structure of electrospun sheets (PLLA shown as an
example), and preliminary results of ALD carried out on
electrospun sheets, as well as discuss the possibilities
of ALD method in functionalization and processing of
electrospun fibres.
