Wherein, the modified carbon nano-tube is prepared according to following technique：CNT is carried out into oxidation processes with acid
Obtain being acidified CNT；To be acidified in CNT addition absolute ethyl alcohol, vinyl trimethoxy silicon will be added at 30-35 DEG C
Alkane, stirring reaction 20-35h is reacted after terminating through filtering, washing, being dried to obtain coupling agent modified CNT；Coupling agent is changed
Property CNT, sodium acid carbonate, neopelex are added to the water, and are stirring evenly and then adding into N- allyl imidazoles and 4- second
Alkenyl biphenyl, the stirring reaction 30-50min at 30-35 DEG C adds sodium peroxydisulfate, stirring reaction 8- after being warming up to 65-75 DEG C
10h, reacts after terminating through being centrifuged, washing, being dried to obtain the modified carbon nano-tube.
Preferably, in its raw material, methyl tetrahydro phthalic anhydride, sebacic dihydrazide, undecyl imidazole, 2,4,6- tri- (diformazans
