Stabilization Study of Modified PAN- co-Polymer Composite Nanofibers
with Functionalized Single-Walled Carbon Nanotubes
In the present study, polyacrylonitrile (PAN)-co-polymer nanofibers as
well as PAN-co-polymer nanofibers reinforced with functionalized single
- walled carbon nanotubes (F-SWCNTs) were produced by electrospinning
and stabilized. The samples were evaluated using DSC, FTIR, SEM and XRD.
In the sample containing F-SWCNT the amount of heat released during the
stabilization reactions was lower than that of pure PAN nanofibers. This
indicates that the F-SWCNT prevents the sudden release of heat and
damage to the nanofibers during stabilization. The carbon nanotubes
greatly prevent the reduction of the diameter of the nanofibers as well
as the decrease in the size of the crystals and the decrease of the
arrangement of the nanofibers during stabilization.
