CONCLUSION
Conductive composite nanofiber of CHT/MWNTs produced using conventional elec-
trospinning technique. A new protocol suggested for preparation of electrospinning
solution, which shows much better stability and homogeneity compared to previ-
ous techniques. Several solvent including acetic acid 1-90%, formic acid, and TFA/
DCM (70:30) investigated in the electrospinning of CHT/MWNTs dispersion. Using
DLS and dispersion stability tests showed that the TFA/DCM (70:30) solvent is most
preferred for nanofiber formation process with acceptable electrospinnability. The
formation of nanofibers with conductive pathways regarding to exfoliated and inter-
conntected nanotube strands is a breakthrough in CHT nanocomposite area. This is a
significant improvement in electrospinning of CHT/CNT dispersion. It has been also
observed that the homogenous nanofibers with an average diameter of 275 nm could
be prepared with a conductivity of 9 × 10
-5
