摘要: Abstract Multiwalled carbon nanotube/polycaprolactone nanocomposites (MWNT/PCL) were prepared by in situ polymerization, whereby functionalized MWNTs (F-MWNTs) and unfunctionalized (P-MWNTs) used as reinforcing materials. The F-MWNTs Friedel–Crafts acylation, which introduced the aromatic amine (COC6H4–NH2) groups on side wall. chemically bonded with PCL chains F-MWNT/PCL, indicated appearance of amide II group FT-IR spectrum. TGA thermograms showed that F-MWNT/PCL had better thermal stability than P-MWNT/PCL. nanocomposite nanofibers an electrospinning technique. contain more 2 wt% not able to be electrospun. bead nanofiber was formed less a relatively broader diameter pure nanofibers. embedded within well oriented along axes electrospun nanofibers, confirmed transmission electron microscopy.
