The method harnesses the power of electrostatic forces to create fibers from a polymer solution or melt, producing fibers with diameters that can range from a few nanometers to several micrometers. The technique was initially discovered in the early 20th century but it wasn’t until the 1990s that the significant potential of electrospun nanofibers was realized and investigated in depth, leading to resurgence in interest and research in the field.

The properties of these nanofibers, their high surface area-to-volume ratio, tunable porosity, and the capability to manipulate their surface properties, make them advantageous for a myriad of applications.

Today, electrospun nanofibers are used across a range of industries and disciplines, from materials science and biotechnology to energy and environmental science.

The world of electrospinning is expansive, consisting of several notable companies that have specialized in different aspects of the technology. From equipment providers that create the machinery necessary for the process, to R&D companies that develop innovative applications of electrospun fibers, these organizations form a significant part of the electrospinning ecosystem.

The necessary equipment for electrospinning can range from relatively simple laboratory-scale setups to more complex and sophisticated industrial-scale systems.

At its core, electrospinning is a fascinating intersection of physics, chemistry, materials science, and engineering.

Its flexibility, coupled with its ability to produce unique and valuable materials, has made it a cornerstone technology in numerous fields.

As we continue to explore its potential and develop new applications and methodologies, the role of electrospinning in our world will only continue to grow.

The electrospinning process can be classified into various types based on the methodology used, each with its unique advantages and specific applications. Here are some key types of electrospinning:

Near-Field Electrospinning

Near-field electrospinning (NFES) is a modified technique of conventional electrospinning, which operates at a much closer distance between the spinneret (needle) and the collector.

The reduced distance allows for direct writing of nanofibers and the ability to control their positioning with higher precision.

However, this method generally has a slower production rate compared to traditional electrospinning and is more suitable for applications requiring precise patterning of fibers, such as in the electronics industry and tissue engineering.

Coaxial Electrospinning

Coaxial electrospinning involves the use of a double-layered needle with two concentric capillaries to generate a sheath and core structure within the fibers.

This allows for the encapsulation of sensitive biological substances or drugs in the core, which can be protected by the sheath material.

It’s particularly used in drug delivery systems and in situations where complex fiber structures are required.

Needleless Electrospinning

As the name suggests, needleless electrospinning doesn’t use a needle or nozzle to produce nanofibers.

Instead, it relies on an edge, usually a rotating disc or cylinder, from which the polymer solution is drawn.

This type of electrospinning allows for higher throughput and overcomes some limitations of traditional electrospinning, such as clogging of needles. It’s often used in industrial-scale production of nanofibers.

Emulsion Electrospinning

Emulsion electrospinning involves creating an emulsion (a mixture of two or more liquids that are normally immiscible) which is then electrospun to create fibers.

The advantage of this method is that it allows for the encapsulation of both hydrophilic and hydrophobic substances, making it a versatile technique particularly useful in the field of controlled drug delivery.

Each of these types of electrospinning has its own set of parameters that need to be optimized, including the type and concentration of polymer, the solvent used the applied voltage, the distance between the needle and collector, the flow rate of the polymer solution, and the environmental conditions such as temperature and humidity.

Electrospun nanofibers are ultrathin fibers that are produced through the electrospinning process. They can be made from a wide range of materials, including polymers, ceramics, metals, or composites, depending on the desired properties and applications.

Due to their small diameter, these fibers exhibit unique properties that are not found in their bulk counterparts, making them highly versatile for a variety of applications.

Definition Of Electrospun Nanofibers

Electrospun nanofibers are fibers with diameters ranging from tens of nanometers up to a few micrometers, although fibers on the smaller end of this range are more common.

They are created by subjecting a viscoelastic fluid, most commonly a polymer solution or melt, to a high electric field, causing it to be ejected from the needle in a process known as electrospinning.

Fabrication Process

The fabrication process of electrospun nanofibers begins with the creation of a polymer solution or melt.

This is then loaded into a syringe and subjected to a high voltage electric field. The electric field causes the solution to be ejected from the needle in a jet that is stretched and thinned as it travels towards a grounded collector, ultimately solidifying into nanofibers.

Properties Of Electrospun Nanofibers

The properties of electrospun nanofibers can be tuned through the selection of materials, electrospinning parameters, and post-treatment processes.

They are known for their high surface area-to-volume ratio, excellent porosity, and high permeability, among other properties.

Additionally, the fibers can be manipulated to have a variety of surface functionalities, morphologies, and structures, such as aligned, random, core-shell, or hollow structures.

Applications And Uses Of Electrospun Nanofibers

Due to their unique properties, electrospun nanofibers have found applications in various fields. In materials science, they are used for the fabrication of filters, sensors, and separators.
