Advanced Fibres and Films

SMITA Research Lab is involved in creating composite fibres at micro and nanoscale. Various anisotropic rigid organic and inorganic nanostructures have been incorporated within different polymer systems to obtain specialty fibres like high performance, high modulus, high tenacity, conducting, carbon fibres etc.


  • Stable dispersion of nanomaterials in the solvent/ polymer system
  • Regulating the spinnability of fibres with the incorporated fillers


  • High initial modulus (4.26 GPa) and high tenacity (~1 GPa) fibre with highly oriented fibrillar structures out of commercial grade nylon 6.
  • Energy efficient process for making carbon fibres with high graphitic content having ID/IG of 2.33.

Nanostructure reinforced nanofibres

The dispersion of nanomaterials in the solution/ melt is the crucial step in making of composite fibres. Investigation on incorporation of nanostructures within the fibre systems were carried out. Different solvent and polymer system like PVA/Water, PVA/Water/DMF and PAN/DMF were studied and Raman analysis confirm that the interaction with the solvent as well as the polymer system results in well dispersed and well aligned incorporation of the nanostructure. PAN nanofibers reinforced with ZnO nanorods up to 50 wt% on the weight of polymer could be readily electrospun in random and aligned configuration.
