Fabrication of micro–nanocapsules by a new electrospraying method using coaxial jets and examination of effective parameters on their production

This paper considers a new method related to the micro and nanocapsules production by using coaxial jets electrospray. The produced micro–nanocapsules were characterized on their structure, mean particles size and morphology by optical and scanning electron microscope. The effects of different operating parameters on the size of the particles were investigated. The obtained results showed the efficiency of the mentioned method in micro–nanocapsules fabrication. The average diameter of fabricated capsules was variable from 80 nm to 900 μm by adjusting different parameters of process.
