Scholarcy highlights

  • Covalent functionalizations, especially oxidization and derivative functionalization, significantly improve the surface characteristics of carbon nanotubes, and bring undesired devastation of sidewalls
  • This paper presents a theoretic model to investigate double-edge effects of covalent functionalization on carbon nanotubes for the polymer composite application
  • For oxidization-based functionalization of originally defect-free nanotubes, the calculation results indicate that about 10% functionalization degree is suggested to be optimum for the balance of efficient load-transfer and conspicuous devastation from the highly covalent functionalization
  • The original defects in nanotube surface reduce the optimum functionalization degree and the reduction is dependent on the original defect concentration
  • Carbon nanotubes with smaller diameter show lower optimum functionalization degree
  • Increasing percentage of carbon nanotubes in the polymer composites leads to lower optimum functionalization degree
