A review. From their unique elec. and mech. properties, carbon nanotubes (CNTs) have attracted great attention in recent years. A diverse array of methods was developed to modify CNTs and to assemble them into devices. From these innovations, many applications that include the use of CNTs were demonstrated. Transparent electrodes for org. light-emitting diodes (OLEDs), lithium-ion batteries, supercapacitors, and CNT-based electronic components such as field-effect transistors (FETs) were demonstrated. Also, CNTs were employed in catalysis and sensing as well as filters and mech. and biomedical applications. This review highlights illustrative examples from these areas to give an overview of applications of CNTs. [on SciFinder(R)]
