ABSTRACT
This chapter presents some insights on carbon nanotube (CNT), functionalization of CNTs, the methods of processing of CNT-rubber nanocomposites, and physical, thermal and mechanical properties of CNT-rubber nanocomposites. CNTs possess high aspect ratio, high surface area and high mechanical properties. The incorporation of CNT in rubber matrix has improved the mechanical, thermal, electrical properties of elastomers. Temperature, gas atmosphere, pressure and laser properties control the CNT properties. In order to enhance the dispersion of multi-walled carbon nanotube in natural rubber, acid modification was carried out. The dispersion level of CNT in elastomeric matrix can be analyzed by microstructural studies. The surface area of CNT is high and its interaction with the macromolecules of rubber will restrict the motion of the molecular chains of NR. The CNT, being a nano-filler with the highest strength and modulus, can be an effective reinforcement to enhance the mechanical properties of rubber.
