AB  - Compared to single-walled carbon nanotubes (SWNTs) and more defective multiwalled 
      carbon nanotubes (MWNTs), the thin few-walled carbon nanotubes (FWNTs) are 
      believed to have extraordinary mechanical properties. However, the enhancement of 
      mechanical properties in FWNTs-polymer composites has remained elusive. In this 
      study, free-standing carbon nanotubes (CNTs)/polymer composite films were 
      fabricated with three types (SWNTs, FWNTs, MWNTs) of functionalized CNTs. The 
      mechanical properties of composite films have been investigated. It is observed 
      that the Young's modulus of composite films with only 0.2 wt % functionalized 
      FWNTs shows a remarkable reinforcement value of dY/dV(f) = 1658 GPa, which is 
      approximately 400 GPa higher than the highest value (dY/dV(f) = 1244 GPa) that 
      was previously reported. In addition, the Young's modulus increased steadily with 
      the increased concentration of FWNTs. The results indicated that FWNTs are 
      practically the optimum reinforcing filler for the next generation of carbon 
      nanotube-based composite materials.
