Electrohydrodynamic atomization (EHDA) is a key research area for producing micro and nano-sized structures. This process can be categorized into two main operating regimes: electrospraying particle generation electrospinning fibre production. Producing particles/fibres of the desired size or morphology depends on factors; properties polymeric solution used processing conditions including flow rate, applied voltage collection distance. In this work particle-fibre transition region was...
