Nanospider™ Electrospinning Technology

Nanospider™ technology is a patented, needle-free high voltage, free liquid surface electrospinning process. The technology is based upon the discovery, that it is possible to create Taylor Cones and the subsequent flow of material not only from the tip of a capillary, but also from a thin film of a polymer solution.

The technology enabled Elmarco to build industrial scale production equipment with out nozzles, needles or spinnerets.

Nanospider™ technology allows the production of nanofibers from polymers solved in water, acids or bipolar solvents and is suitable for the production of organic high quality fibers. This versatile technology is easily adapted to a variety of process parameters for the optimization of the specific properties of the produced nanofibers.



Nanospider™ technology uses simply shaped electrodes, has no parts easily clogged 
(in comparison to needle-type electrospinning) and is generally mechanically simple. 

Productivity & Quality

The numbers of fibers per machine width is given by the distance of the Taylor cones. Nanospider™ free liquid surface electrospinning lets natural physics define this distance, rather than using individual needles. This allows higher fiber packing density and thus an increased productivity as well as better fiber homogeneity and more consistent web morphology.


Nanospider™ technology is flexible to allow the production of a nanofiber layer which best meets your final product needs. Elmarco is able to help you optimize the critical parameters:

  • Nanospider™ equipment configuration
  • Polymer system properties and selection
  • Substrate material properties and selection


Nanospider™ technology allows optimizing the results in nanofiber production through precise adjustment of many process parameters, which are decisive for final product:

  • Solution parameters (conductivity, temperature, surface tension, etc.)
  • Environmental parameters (temperature, humidity etc.)
  • Base material parameters (cross and surface electrical resistance, etc.)
  • Equipment parameters (voltage, electrode distance, etc.)



  • High productivity & scalability
  • High fiber diameter and web uniformity
  • Economical operation and easy maintenance
  • Flexibility in used polymers and substrates

Nanofibers are highly engineered textiles defined as fibers with diameters less than 500 nm. Researchers around the globe are developing new uses for nanofibers in the broadest imaginable range of applications. Nanofibers often become a unique component of materials integrated deep inside of finished products. 

Elmarco works with customers and researchers to demonstrate how nanofibers can benefit end products as well as to develop totally new materials or solutions to improve final product and find new applications. The Nanospider™ technology provides an easy scale up from laboratory to industrial scale and its high volume production capability accelerates nanofiber products introduction into the market.   

Nanofiber materials are used in a fascinating array of end products. This section highlights only a few application areas and end products which benefit from the use of nanofibers. Readmore
