Transitioning Concepts into Working Prototypes
NEI Corporation offers electrospinning services for producing nanoscale and microscale fibers. We use our knowledge and expertise to help transition your concepts into working prototypes. Electrospinning is a technique to form fibers by the use of a voltage potential between a solution of the material and a grounded collector. The process elongates the fiber as it is formed, yielding fiber diameters typically in the range of 50 to 500 nm. The electrospinning equipment at NEI allows for large areas of fiber mats, upwards of one square foot. Combined with a variety of characterization and testing equipment already available in-house, this can accelerate development of the customer’s technology into commercial materials.

Available Services
NEI’s versatile electrospinning services can produce multi-scale, multifunctional, nanoscale and micron-sized fibers, providing an advantage over conventional fiber production technology. We can incorporate nanoparticles into electrospun fibers, produce core-sheath fibers, and fabricate composites of electrospun fibers embedded in polymer matrix composites. Fibers can be produced for a broad array of applications, such as protective clothing, filters, tissue engineering, biotechnology, and optical electronics. Learn more below or request a quote.

Core-Sheath Fiber Spinning
Should your application include biomimetics, microfluidics, or a host of other novel technologies, NEI will work with you in developing the next state-of-the-art, multi-core fibers. Typically, there is a specified core material and a different sheath material. Such a system can be envisioned as a drinking straw where the tube of the straw is a material, such as a polymer or ceramic, that contains another material in the core (even liquids).
Exploratory Prototyping
Whether your vision is polymer, ceramic, or metal fibers – single core or multi-core – NEI has the right tools and expertise to help you realize your ideas into the next great innovation. The world of advanced nanometer-scale fibers is rapidly expanding as new breakthroughs are made each day. We can help you transfer these breakthroughs into working prototypes by providing the appropriate environment and equipment to produce electrospun fibers.
NEI can also assist the customer in identifying the special attributes of electrospun fibers and how to benefit from them. NEI has worked with other companies to elevate the technology readiness levels of new technologies and can provide direction in advancing fiber production as per the needs of the application. Characterization and tests can be carried out under applicable industry standards, such as American Society for Testing and Materials (ASTM).
Applications
Electrospun fibers can be used in a variety of applications, such as:
- Environmental Engineering – electrospun nanofiber meshes make excellent filtration membranes for waste water treatment and particle removal from air.
- Biomedical Engineering – electrospun nanofibers have been intensively investigated as a scaffold material for tissue engineering.
- Energy Storage – electrospun nanofibers can be used in all three layers of a lithium-ion battery to enhance the overall battery performance, including large capacity, high charge / discharge rate capability, and extended cycle life.

NEI White Paper
Exploring the Capabilities of Electrospinning »
Among the several methods to make nanofibers, electrospinning is deemed the most promising due to its ability to produce continuous nanofibers on a large scale and adjustable fiber structures from a variety of electrospinnable polymers. Here, we review the morphology of electrospun nanofibers and the various parameters and versatile techniques used to transform a wide range of polymers and ceramics into fiber structures. We also explore the growing number of applications… continue reading »
Electrospun Mats
Electrospun Mats »
NEI offers electrospun mats of PAN, PVA, and PVDF-HFP fibers. Each mat is a free standing flexible sheet with microstructural features not available from a bulk material.
Standard electrospun mats are either 4″ x 4″ (10 cm x 10 cm) or 8″ x 11″ (20.3 cm x 28 cm) with a typical thickness of 1 mil (25 microns). However, the dimensions and thickness can easily be adjusted as per the customer’s specifications.
