Preparation and Properties of Mutilwalled Carbon Nanotubes/Polyacrylonitrile Composite Nanofiber Sheets

摘要

Continuous composite nanofiber sheets made from polyacrylonitrile (PAN) and surface-oxidized multiwall carbon nanotubes (MWCNTs) were successfully fabricated by electrospinning. The rheological property of PAN/MWCNTs solution was studied by capillary rheometer and the surface morphology of composite nanofiber was observed by scanning electron microscopy (SEM). The dispersion of MWCNTs played an important role in electrospinning. The mechanical properties of composite nanofiber paper were discussed by the traditional stress-strain mode.
