In order to evidence the interaction of DMIC and CNTs, a small amount of the dried DMIC/CNT mixture was thoroughly washed by ethanol and water, respectively, andthen the remaining DMIC amount in the mixture was quantified by the TGA. The TGA curves of the washed DMIC/CNT mixtures,which were received upon washed by ethanol and water, respectively, are shown in Fig. 2a.
