Tuning the compressive mechanical properties of carbon ...

2011-8-15  In addition to excellent compressive strength, the CNT ar-ray foams exhibited high thermal resistance. A foam-like CNTarray was heated to 500 C in air for 30 min.Fig. 8shows thecompressive strength of the array prior to and after the ther-mal treatment. Both of the tests were conducted on the sameCNT array in different locations. The loading and unloadingcurves showed minimal change before and after the treat-ment. The thermal resistance matches the performance ofaluminum foams and far exceeds the operating temperaturefor polymeric foams. High temperature silicone and polyim-ide foams have a maximum use temperature of 250 C.Polyurethane foams have a glass transition point of 50 to20 C. Below this transition point, recovery of the foamwill not occur and the total energy absorbed by individualpolymer chains decreases. CNTs do not exhibit the majortemperature transitions that influence bulk polymer proper-ties. Thus, CNT array foams
