Invention

Cornell researchers have developed a novel electrospinning device and method capable of delivering superior quality nanofibers with controlled fiber solidification.  Using electrically and thermally insulating materials in a heating unit, the device can better control melt characteristics without compromising electrospinning motions.  The result is a much improved electrospinning process that can produce fibers from a variety of materials including polyethylene, polypropylene, etc.
