Abstract
Various structures of particles were prepared by electrospray technique. In this research, solid particles were formed by electrospraying a solution of ethanol containing polyvinyl and tetraethyl orthosilicate. During the electrospray process, the ethanol solvent was evaporated, resulting in the solidification of precursors, forming solid particles. Evaporation of ethanol solvent also enhanced the mass transport which facilitated the development of porous and hollow structures.
