PET/TPU nanofiber composite filters with high interfacial adhesion strength based on one-step co-electrospinning

Studies of Interfacial Interaction between Polymer Components on Helical Nanofiber Formation via Co-Electrospinning

Helical fibers in nanoscale have been of increasing interest due to their unique characteristics. To explore the effect of polymer type on helical fiber formation, three polymer systems, Poly(m-phenylene isophthalamide) (Nomex)/polyurethane (TPU), polystyrene (PS)/TPU and polyacrylonitril (PAN)/TPU are used to fabricate helical nanofibers via co-electrospinning. Differential scanning calorimetr...

Electrospinning of Continuous Nanofiber Bundles and Twisted Nanofiber Yarns

Spinning is a prehistoric technology in which endless filaments, shorter fibers or twisted fibers are put together to produce yarns that serve as key element to assemble multifarious structural designs for diverse functions. Electrospinning has been regarded as the most effective and versatile technology to produce nanofibers with controlled fiber morphology, dimension and functional components...

An Injectable Nanofiber-Hydrogel Composite with Interfacial Bonding for Soft Tissue Filling and Regeneration.

INTRODUCTION: Restoration of acquired, congenital, or age-related soft tissue defects using autologous or implantable materials can cause donor site morbidity, infection, device failure, and fibrosis. Injectable fillers are limited by variable resorption and fat grafting causes necrosis in large volumes. An alternative approach using the body’s regenerative capacity and an injectable synthetic ...

Microscale electrospinning of polymer nanofiber interconnections

Electrospinning collagen and hyaluronic acid nanofiber meshes.

Collagen and hyaluronic acid (HA) are main components of the extracellular matrix and have been utilized in electrospinning; a technique that creates nanosized fibers for tissue scaffolds. A collagen/HA polymer solution was electrospun into a scaffold material for osteoporosis patients who have reduced bone strength. To synthesize nanofibers, a high voltage was applied to the polymer solution t...
