AB  - Carbon nanotubes (CNTs) are widely investigated for preparing polymer 
      nanocomposites, owing to their unique mechanical properties. However, dispersing 
      CNTs uniformly in a polymer matrix and controlling their 
      entanglement/agglomeration are still big technical challenges to be overcome. The 
      costs of their raw materials and production are also still high. In this work, we 
      propose the use of CNTs grown on oil fly ash to solve these issues. The CNTs of 
      oil fly ash were evaluated as reinforcing materials for some common 
      thermoplastics. High-density polyethylene (HDPE) was mainly reinforced with 
      various weight fractions of CNTs. Xylene was used as a solvent to dissolve HDPE 
      and to uniformly disperse the CNTs. Significantly enhanced mechanical properties 
      of HDPE reinforced at a low weight fraction of these CNTs (1-2 wt.%), mainly the 
      tensile strength, Young's modulus, stiffness, and hardness, were observed. The 
      tensile strength and Young's modulus were enhanced by ~20 and 38%, respectively. 
      Moreover, the nanoindentation results were found to be in support to these 
      findings. Polycarbonate, polypropylene, and polystyrene were also preliminarily 
      evaluated after reinforcement with 1 wt.% CNTs. The tensile strength and Young's 
      Modulus were increased after reinforcement with CNTs. These results demonstrate 
      that the CNTs of the solid waste, oil fly ash, might serve as an appropriate 
      reinforcing material for different thermoplastics polymers.
