Abstract
Electrospinning of natural polymers is often difficult
compared to electrospinning of synthetic materials.
Typical problems concerning natural materials are finding
of applicable solvent, low molecular weight, contracted
molecular conformation in solution, and charged groups in
their structures. Electrospinnability of some natural
materials can be enhanced by chemical modification of
polymer, adjusting the electrospinning conditions and
using auxiliary polymer. In this study electrospinning
trials were carried out using three natural polymers.
These materials included milk proteins (casein), lignin
and cellulose. Na-caseinate was soluble in water, and it
was electrospinnable with auxiliary polymers. Lignin
formed fibers with different solvent and auxiliary
polymers, but also pure lignin fibers were obtained.
Cellulose material was derivatized in order to obtain
solubility in water. Electrospinning of cellulose proved,
however, to be challenging
