A kind of preparation method of the grafted by super branched polymer carbon nanotube based on click chemistry

The preparation method for the grafted by super branched polymer carbon nanotube based on click chemistry that the present invention relates to a kind of, its step are as follows: 1) being handled using concentrated nitric acid carbon nanotube, obtain acid processing carbon nanotube；2) lead to peracid treatment carbon nanotube to react to obtain grafting carbon nanotube containing mercaptosilane coupling agents with containing mercaptosilane coupling agents；3) esterification is occurred by alkynes butanol and mercaptopropionic acid and hyperbranched monomer is made；4) using alkynyl contained by the sulfydryl and hyperbranched monomer on grafting carbon nanotube containing mercaptosilane coupling agents as reaction active groups, using ultraviolet light-initiated sulfydryl-alkene click-reaction, grafted by super branched polymer carbon nanotube is finally obtained.The invention has the following advantages that passing through light-initiated carry out click-reaction; reduce solvent usage; simplify post-processing step; be conducive to large-scale production; dissaving polymer clad by being grafted on carbon nano tube surface formation increases carbon nanotube surface layer active function groups, is conducive to further using for carbon nanotube.
