A Simple Homemade Electrospinning for Nanoscale Fibres Production

摘要

A high technology often is required by electrospinning device to produce a nanoscale fibre. This requirement results in difficulties to get the device simple design and operate with reasonable price. This paper presents the work to implement design of the electrospinning system. This electrospinning system consists of a main construction body, an electrical power supply to provide a voltage source direct current form, a syringe pump and a flat collector. The main body are made of acrylic with knockdown construction since acrylic is an easy material to shape. The power supply has a simple main single switch with high ferite transformer to produce high dc voltage through a diode – capacitor filtering. A used medical syringe has been modified as an injection pump to spray the materials into fibre form. A simple flat metal has been reconstructed to be electrode – ground collector to receive fibre product. The test was carried out using polyaniline materials. The general parameters in the production process are resolution of the spraying rate μ? / minute and the power supply provide electricity in kiloVolt. The result of fibre production observed by using SEM shows that the electrospinning device successfully produces fibres on a nanometer scale.
