Abstract: The fundamental mechanisms on the needleless electrospinning were described. The three typical approaches to induce perturbed surface waves during needleless electrospinning, namely magnetic field, aerated solution bubbling, and rotating disc electrodes, were introduced, with their principles, features and applications analyzed. The advantages of needleless electrospinning in feasibility and efficiency over needle electrospinning were confirmed in the experiments using rotating disc electrode method.

Key words: electrospinning, needleless electrospinning, perturbation surface, rotating electrode
