ABSTRACT
Carbon nanotubes (CNTs) have many desirable bulk properties, such as very good mechanical strength, high thermal stability, and excellent electrical conductance for potential use in a variety of applications. However, their surfaces often require modication in order to achieve functionality. To help control electronic properties, electron-withdrawing oxygen and halogen atoms may be covalently bonded to the surface to assist in the conversion of metallic-like conductivity of CNTs to semiconducting properties.
