Development of Low Dielectric Material Using Carbon Nanotubes

Abstract

We have developed low dielectric material using carbon nanotubes and measured its microwave‐absorbing properties. Its mechanical properties have also been investigated. Measurement showed that tensile strength increases by 23% and tensile modulus increases by 36%. A plausible explanation for high increase of mechanical properties has also been discussed.

Keywords:

• carbon nanotube (CNTs)
• dielectric constant
• dissipation factor
• tensile strength, tensile modulus
