Abstract:

In recent times, electrospinning has become a well known and widely investigated process used for manufacturing nano or/and micro fibres with electrostatic forces between two electrodes. Various additives such as silver, starch, copper, etc. are used in electrospinning to achieve specific properties. Amber is a natural material which has a positive influence on human health and wound healing. However, no information about the electrospinnig of amber particles has been found. In this paper, the possibility of electrospun nanofibrous web formation via electrospinning equipment (NanospiderTM) from poly(vinyl alcohol) solution with solid particles of Baltic amber is presented. It was determined that the maximum size of amber particles which can be transferred from the solution to the electrospun web is around 50 μm, while the probable optimal size of amber particles for electrospinning is below approximately 10 μm.
