Nanofiber

Nanofiber is a fiber in the nanoscale. They can be manufactured by various processes such as polymerization, electrospinning and electrostatic spinning, and melt processing. Nanofiber can be fabricated from different kind of inorganic substances, such as titanium dioxide, silicon dioxide, zirconium dioxide, aluminum oxide, lithium titanate, titanium nitride or platinum.

Nanofibers are used in many application including nanomedicine, biomedicine, textile manufacturing and modification, filtration systems, water and air purification, energy cells and batteries.

  • A Nano-Roundabout for Light

    At TU Wien, it was possible to create a nanoscale optical element that regulates the flow of light particles at the intersection of two glass fibers like a roundabout. A single atom was used to control the light paths. Just like in normal road traffic, crossings are indispensable in optical signal processing. In order to avoid collisions, a clear traffic rule is required. A new method has now been developed at TU Wien to provide such a rule for light signals. For this purpose, the two glass fibers were coupled at their intersection point to an optical resonator, in which the light circulates and behaves as in a roundabout. The direction of circulation is defined by a single atom coupled to the resonator. The atom also ensures that the light always leaves the roundabout at the next exit. This rule is still valid even if the light consists merely of individual photons. Such a roundabout will consequently be installed in integrated optical chips – an important step for optical signal processing.

    Cavity-enhanced Raman-scattering reveals information on structure and properties of carbon nanotubes. The inherently weak signals are amplified by using special micro cavities as resonator, giving a general boost to Raman spectroscopy as a whole.

  • 혁신적 전기방사 기술을 이용한 나노섬유 생산 기술 (New Electro blown spinning process for Nanofiber production)

    전기방사에 의한 나노섬유 제조공법은 각종폴리머를 solvent(용제)에 녹인 후 이를 고전압(± 10KV)을 가해 자기장을 형성후 이 사이에서생기는 전기적 반발력을 이용해 방사되는 고분자용액을 나노급의 섬유로 뽑아내는 기술입니다. 

    Electro spinning is a process that produces a highly impermeable, non-woven nano-fabric of sub-micron fibersby pushing a millimeter diameter liquid jet through a Nozzle with an electric field (fibrillation of fiber).
