3. Applications of NTCs

Due to their intrinsic properties (size, elasticity, conductivity, aspect ratio, etc.), numerous applications for NTCs have been considered. Nanotubes are 100 times stronger than steel, yet weigh only one-sixth as much, making them very attractive for use in composite materials for aeronautics and space applications. They have very high elasticity and a nanometric diameter, which are excellent qualities for use as nanoprobes for atomic force microscopy (AFM). Studies are focusing on the use of CNTs for storing hydrogen or other gaseous fuels. All these applications account for less than a third of publications on CNT applications, which mainly target electronics at the micron or nanometer scale. Prototypes of CNT-based sensors have been developed, taking advantage of their specific surface area or the potential to functionalize them
