Abstract:
Carbon nanotube (CNT) foams have received an overwhelming response in research community
due to their large strength to weight ratio. In this work, CNT foam was prepared using functionalized CNT. Pore size distribution in synthesized CNT foams was observed to be in the range
200–400 lm and porosity is in range 60–65%. The bulk density of foam is 0.2–0.3 g/cc.
Furthermore, uniaxial compression tests at varying rates, indicates deformation behavior to be rate
dependent. Cyclic compression test was also performed showing similar behavior to cellular materials; hysteresis loop is found in loading–unloading cycles, clearly indicating energy dissipation.
