Abstract Electrospinning is a simple and cost-effective technique for manufacturing of fibers that diameter in nano-scale. The continuous jet is spun from the capillary needle with a polymer solution to ground under a high electric field. Nanofibers that were produced using this technique offer the potential for a wide variety of applications such as filtration for air or water, tissue engineering scaffolds, protective clothing and biomedical application etc., due to the exceptional properties, for instance, high specific surface area, high aspect ratio and much smaller pore size. Therefore, an electrospinning system was set up in this study. The purposes of this study include: (a) the effects of concentration of PMMA solution, sodium chloride volume, feed rate and distance from needle tip to collector (spinning distance) on electrospun nanofiber characteristic, (b) applied to collection of particles under different conditions that were fiber types, face velocity, fiber diameter and surface voltage of the fibrous membrane. PMMA nanofibers were successfully produced by electrospinning technique in this study. The diameter of electrospun fiber was increased and the beaded count of fiber was decreased if the concentration of polymer becomes higher. However, both the beaded count and average diameter of fiber could be decreased if the sodium chloride was added into PMMA polymer solution. In addition, average diameter of fibers decreased as spinning distance increased. The fiber film was applied to collect particles. The results showed the good penetration in collection of particles. In some specific parameters, the best penetration is about 3.0×10$^(-5).
