Abstract
The invention belongs to the technical field of materials, and particularly relates to a preparation method for an in-situ grafting carbon nano tube containing benzoxazole ring polymer. According to the method, 4-halogenate carboxylic ester benzocyclobutene is grafted to a multi-wall carbon nano tube by Diels-Alder reaction, atom transfer radical polymerization initiates the polymerization of N-(o-hydroxyphenyl) acrylamide monomer, and a product is subjected to thermal cyclization so as to obtain the in-situ grafting carbon nano tube containing the benzoxazole ring polymer. The method has theadvantages that: the damage and cutting of the carbon nano tube, which are caused by acid treatment, can be avoided; the structural integrity of the carbon nano tube is kept; the in-situ grafting carbon nano tube containing benzoxazole ring polymer, which is obtained by the atom transfer radical polymerization, is uniform in performance; grafting polymers are connected with each other through delocalized pi bonds of the carbon nano tube so as to form a unique conjugated system; and the in-situ grafting carbon nano tube containing the benzoxazole ring polymer has wide application prospect in the aspects of semiconductors, antistatic materials, anode materials, electromagnetic shielding and structure stealth materials and the like.
