For the two kinds of CNTs and for each preparation, TGA provided the calculation of the percentage of polymer correctlyadsorbed onto the nanotube. Preliminarily, the typicalthermogravimetric behavior of the two polymers PEI (Fig. 1A) andPAMAM (Fig. 1B) as well as the two nanotubes CNT (Fig. 1C) andCNT-COOH (Fig. 1D) was defined as a result of the thermallyinduced decomposition in the range 20e800 C.Two main releasing steps may be observed in Fig. 1A for PEIcorresponding to the thermally induced decomposition of thepolymer respectively at 385.9 ± 0.1 C and 462.9 ± 0.2 C. Threemain releasing steps can be described for PAMAM (Fig. 1B): the firstis related to the loss of the residual solvent while the remaining twoderived from the decomposition process of the polymer respectively at 312.9 ± 0.2 C, 429.0 ± 0.6 C and 598.6 ± 0.3 C.Regardless to the nanotubes, the pristine form (Fig. 1C) remainsstable until 620 C with a decomposition temperature of about664.4 ± 0.1 C, while for the carboxylated one (Fig. 1D) a slightydecease in the thermal stability may be observed as a consequenceof the functionalization with a decomposition temperature of about650,9 ± 0.1 C.For each preparation, the resulting TG and DTG curves corresponding to uncoated nanotube (blue), polymer and functionalizednanotube (green) were overlapped and reported in Fig. 2, in orderto identify different decomposition processes that permit tocalculate the percentage of PEI and PAMAM.With the aim of providing the most performing procedure forcoating nanotubes, three main aspects were taken into consideration: the selection of the polymer with the better affinity to thenanotube; the identification of the suitable concentration of polymer between the 40% and an exceeding amount; and the evaluationof the time required for the most performing coating procedureamong 24 h, 48 h and 72 h. The calculation of the percentage ofpolymer adsorbed in each coated nanotube provided preliminarlyinteresting results, as reported in
