Creating Tubular Nanofibers with NANON

Nanofiber technology holds great promise for a wide range of applications.
In this post, we introduce tubular nanofibers—a unique structure that can be created using our electrospinning device, NANON.

What Are Tubular Nanofibers?

At our company, we produce straw-like tubular nanofibers by rotating mandrel rods with diameters ranging from 2 mm to 10 mm while spraying a solution jet onto them. These fibers are expected to be applied in a variety of fields, such as medical uses like artificial blood vessels and energy devices. In particular, when using biocompatible polymers, applications in cutting-edge medical fields—such as tissue engineering and drug delivery systems—are expanding.

Fabrication of Tubular Nanofibers Using NANON

In this demonstration, we created tubular nanofibers using the following setup:

• Device: NANON (Electrospinning device)
• Collector: Mandrel collector (rotating cylindrical collector)
• Material: Polyurethane (PU) solution

Features of Our Tubular Nanofibers

・Uniform Structure
　The high-speed rotating mandrel collector enables the formation of smooth and consistent nanofibers.

・High Versatility
　Applicable to a wide range of uses, including filters, biomedical applications, and energy devices.

・Flexible Design
　The diameter and thickness of the fibers can be controlled by adjusting the size and rotation speed of the collector.

Future Outlook

As we further advance our tubular nanofiber fabrication technology, we aim to develop materials with even more sophisticated functions. In particular, we anticipate expanded use in the medical field, such as artificial blood vessels and drug delivery systems.

Our company continues to enhance our electrospinning technology, striving to provide equipment capable of producing various types of nanofibers. We also actively support researchers and companies by offering equipment customization and tailored operation methods to help them explore new application areas.
