Process for Making pure, Blended, and Coaxial Fire-resistant Nanofibers

Description:

This technology involves dissolving a flame-resistant polymer in a solvent, such as acetonitrile or dimethyl sulfoxide, and combining it with a solution of a common polymer, like polyacrylonitrile, at various concentrations. Through electrospinning, these solutions are transformed into fibers with controlled diameters and orientations, resulting in mats with specific structural properties. The process allows for the creation of both uniaxially aligned and bidirectionally oriented fiber mats, as well as coaxial fibers, by adjusting the electrospinning parameters and setups, including the use of syringe pumps, voltage adjustments, and target configurations.

Key Advantages:

• Enhanced flame resistance in polymer materials.
• Precise control over fiber diameter and orientation.
• Versatility in producing both uniaxially and bidirectionally oriented fiber mats.
• Capability to create coaxial fibers for advanced material properties.
• Applicable to a wide range of polymer types and solvent systems.

Problems Solved:

• Improvement of fire safety in materials.
• Lack of control in fiber orientation and structural properties in existing materials.
• Difficulty in integrating flame-resistant properties into common polymers.
• Challenges in producing materials with customized mechanical and thermal properties.

Market Applications:

• Fire-resistant clothing and gear.
• Advanced composite materials for aerospace and automotive industries.
• Protective coverings and coatings with enhanced fire safety.
• High-performance filtration systems.
• Electrical insulation with improved safety features.
