Inorganic nanofibers available on industrial scale

Kertak Nanotechnology s.r.o. (Ltd.) is a supplier of inorganic nanofibers produced by industrial-scale electrospinning technology. Thanks to this technology we take the position of the world leader in the production of electrospun inorganic nanofibers!


Founded in 2009;

Located in the Czech Republic (Central Europe);

Number of employees: 15 and still growing;

Production capacity: tons of inorganic nanofiberous material annually.



Kertak Nanotechnology is using a unique technology based on the electrospinning process. This technology enables the production of non-polymer nanofibers on the basis of inorganic substances mainly on TiO2, Li4Ti5O12, Al2O3, SiO2, ZrO2 or Pt on an industrial scale with production capacity of tons of material p.a. This unique and advanced processing technology enables us to achieve controllable product parameters such as:


  • composition: possibility to produce a number of kinds of inorganic substances (e.g. TiO2, SiO2, ZrO2, TiN, NiO, Ni, CuO, Cu etc.) with desirable crystal structure (e.g. ZrO2 as monoclinic, tetragonal or cubic crystal structure)
  • purity and doping: possibility to modify nanofiberous material in respect to its  purity and doping level with various elements (e.g. TiO2 can be doped with noble metals) 
  • nanofiber size: possibility to modify the dimensions of nanofiber product (diameter of fibers)
  • specific surface area



  • Industrial production of inorganic nanofibers (TiO2, SiO2, ZrO2, Al2O3, Li4Ti5O12);
  • Development of new nanofiberous materials (laboratory scale:In2O3,ZnO, SnO2, WO3, CeO2, LiFePO4 and many other oxide, carbide and nitride nanofiberous materials);
  • Customization of parameters of inorganic nanofibers in accordance to customers demand;
  • Post treatment of inorganic nanofibers - preparation of dispersions, doping, cutting, milling, etc;
  • DEVELOPMENT OF FINAL APPLICATIONS based on inorganic nanofibers;

Thanks to our experiences and know how, we take the position of global

leader in development of final applications and novel nanofiberous materials.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at
