Introduction

The field of electrospinning has gained significant attention in recent years due to its potential in producing nano fibers with unique properties. These nano fibers have a wide range of applications in various fields, including textiles, medicine, and filtration. However, the production of these nano fibers requires a precise and controlled electrospinning process, which can be challenging to achieve. In this study, we designed an electrospinning tool that utilizes a flyback as a high voltage power supply and a stepper motor as a syringe drive to produce nano fibers from polymer material, specifically polyvinyl alcohol (PVA).

Designing Electrospinning Tools with Flyback as High Voltage Power Supplies: Towards Nano Fiber Production

The electrospinning tool designed in this study consists of a horizontal configuration with collectors on the front and coated with aluminum foil. This allows the polymer solution jet to move horizontally to the collector. The PVA solution is injected into the spinneret, and the electrospinning tool is operated in a voltage range of 15 kV - 25 kV with a spinneret-collector distance of 8 cm. The results showed success in producing nano fibers with non-continuous morphology and diameter ranging from 125-198 Nm.

The use of a flyback as a high voltage power supply in the electrospinning device has several advantages. High efficiency: Flyback is able to produce high voltage with high efficiency, thus minimizing energy loss and producing a more stable electrospinning process. Compact size: Flyback has a relatively small size, so that it allows the design of electrospinning tools that are more concise and easy to implement. Voltage control: Flyback can be controlled to regulate the resulting output voltage, allowing precision settings in the electrospinning process.

The Uniqueness of this Electrospinning Tool Design

The horizontal system design in this electrospinning tool allows easier observations to the process of forming nano fibers. The use of a stepper motor ensures the flow of polymer solution is controlled and accurate, thus helping in producing nano fibers with a uniform diameter. The aluminum foil in the collector functions as a conductive nano fiber collector surface, so as to minimize the static charge effect on the resulting nano fiber.

Potential for Development and Application

This study opens opportunities for further development in making electrospinning tools with more optimal and efficient designs. With a more precise voltage control and the ability to control the speed of the motor stepper, nano fibers can be produced with morphology and more uniform diameters. Nano PVA fiber produced through this process has a broad application potential in various fields, such as:

Textile: Nano PVA fiber can increase the resistance, strength, and absorption of fabric.
Medical: Nano PVA fiber can be used in the manufacture of wound pads, medical filters, and tissue scaffold.
Filter: Nano PVA fiber can be used in making air filters and more efficient water filters.
Sensor: Nano PVA fiber can be used in making sensors that can detect environmental changes, such as humidity or temperature.
