**1.2. Physical properties of carbon nanotubes**

**Figure 1** illustrates the comparison of SWCNTs properties against all known materials. For instance, the electrical conductivity is 1000 times higher than cooper, Young modulus almost same as diamond, tensile strength up to 14 times higher than Kevlar and thermal conductivity almost same as aluminum.

### **1.3. Potential applications of carbon nanomaterials**

In **Figure 2**, we select some of the potential applications for SWCNTs. One of the interesting application of SWCNTs is hydrogen storage. SWCNTs have high surface area; curvature creates cavities of molecular dimensions and superpositions of potential fields in cavities lead to large attractive force on hydrogen molecules [5]. SWCNTs are capable of adsorbing hydrogen quickly, to high density, at ambient temperatures and pressures [6–8]. The SWCNTs have been used in different types of applications such as biosensors [9], chemical sensors [10], scanning microscope tips [11], nanoelectronics [12], and third generation solar cell [13].
