Electrospraying (electrohydrodynamic spraying) is a method of liquid atomization by electrical forces. Spraying solutions or\nsuspensions allow production of fine particles, down to nanometer size. These particles are interesting for a wide variety of\napplications, thanks to their unprecedented chemical and physical behaviour in comparison to their bulk form. Knowledge of the\nparticle size in powders is important in many studies employing nanoparticles. In this paper, the effect of some process parameters\non the size of electrosprayed polyacrylonitrile particles is presented in the form of response surface model.The model is achieved\nby employing a factorial design to evaluate the influence of parameters on the polyacrylonitrile nanoparticle size and response\nsurface methodology. Four electrospraying parameters, namely, applied voltage, electrospraying solution concentration, flow rate,\nand syringe needle diameter were considered.
