Electrospinning

Electrospinning Services

NEI Corporation offers electrospun mats, as well as 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.

Electrospun Mats NEI offers:

Electrospun PAN is an ultrafine mat of polyacrylonitrile
Electrospun PVA is an ultrafine mat of polyvinyl alcohol
Electrospun PVDF-HFP is an ultrafine mat of poly(vinylidene fluoride-co-hexafluoropropylene)

Additional Services

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).
