Influential Factors on Formation of Nanofibers: Assessments of Electrostatic Spinning Parameters

Jia-Horng Lin, Meng-Chen Lin, Mong-Chuan Lee, Chao-Tsang Lu, Chien-Lin Huang, Ching-Wen Lou


Nanofibers have a high specific surface area and a high porosity, and thus have been applied to many fields. Electrostatic spinning is one efficient and convenient method for the preparation of nanofibers. Two influential factors of the formation of nanofibers include processing parameters, such as voltages and velocity, and environmental factors, such as temperatures and humidity. This study uses a home-made electrospinning machine for the production. The morphology of the resulted nanofibers is examined in terms of the processing parameters, in order to provide f more feasible applications. The test results indicate that the viscosity of PVA electrospinning solution becomes dense as a result of the increasing temperatures. An increasing voltage changes the morphology of nanofibers from being smooth to rugged. Moreover, the diameter of nanofibers becomes smaller when the electrospinning distance is increased. *
