^a𝐷_SEM: surface pore diameter derived by Image Analysis of SEM micrographs. ^b𝐴_BET: buckypaper surface area obtained through Brunauer, Emmett and Teller (BET) analysis of isotherms derived from nitrogen adsorption/desorption measurements [20]. ^cAverage internal pore diameter. ^dObtained through application of Horvath-Kawazoe (HK) and Barrett, Joyner and Halenda (BJH) methods to isotherms derived from nitrogen adsorption/desorption measurements [21, 22]. ^eAverage nanotube bundle diameter. ^fInsufficient data to enable calculation of this value. ^gData taken from [14].
