Nanoyarns: Recent Advancements in Production Techniques, Applications, and Future Prospects

Nanoyarns hold promises for many different applications with their higher tenacity, durability, and uniformity as a reinforced version of nanofibers. The most common production technique in nanoyarn production is electrospinning as it is a well-known and widely accepted method for manufacturing nanofibers. Nanofiber yarns via centrifugal spinning were introduced by FibeRio Corporation along with their patent issued in 2009. Centrifugal spinning uses centrifugal forces to elongate polymer jets so that they can be transformed into nanofibers. Nanoyarn production via solution blowing is a relatively new technique in comparison to electrospinning and centrifugal spinning. Nanoyarns find uses in many areas from tissue engineering to drug delivery, energy, and sensory applications due to superior properties such as large surface area, regeneration, improved delivery, power generation, and sensing. Potential applications are only limited by imagination while considering feasibility, cost, and consumer preferences. New designs of collectors may open up new possibilities for differentiated alignment and morphology developments of nanoyarns.
