Abstract
(EN)
Disclosed are a modified carbon nanotube, and a preparation method and an application thereof. The preparation method of the modified carbon nanotube comprises the following steps: subjecting 1,2:5,6-dioxyisopropylidene-D-glucofuranose and an anhydride as raw materials to an esterification reaction to obtain a monomer of 1,2:5,6-dioxyisopropylidene-D-glucofuranose ester, the anhyride includes at least one unsaturated double bond structure; subjecting the monomer of 1,2:5,6-dioxyisopropylidene-D-glucofuranose ester to a homopolymerization reaction to obtain a polymer of 1,2:5,6-dioxyisopropylidene-D-glucofuranose ester; reacting the polymer of 1,2:5,6-dioxyisopropylidene-D-glucofuranose ester with a weak acid to obtain a polyglucose ester, and subjecting the polyglucose ester to a grafting reaction with a carbon nanotube to obtain the modified carbon nanotube. By using a glucose group-containing polymer to modify a carbon nanotube, the preparation method of the modified carbon nanotube can be applied to prepare a reagent for detecting a cancer cell.

L'invention concerne un nanotube de carbone modifié, ainsi qu'un procédé de préparation et une application associée. Le procédé de préparation du nanotube de carbone modifié consiste : à soumettre du 1,2:5,6-dioxyisopropylidène-D-glucofuranose et un anhydride en tant que matières premières à une réaction d'estérification pour obtenir un monomère d’ester de 1,2:5,6-dioxyisopropylidène-D-glucofuranose, l'anhyride comprenant au moins une structure à double liaison insaturée ; à soumettre le monomère d’ester de 1,2:5,6-dioxyisopropylidène-D-glucofuranose à une réaction d'homopolymérisation pour obtenir un polymère d’ester de 1,2:5,6-dioxyisopropylidène-D-glucofuranose ; à faire réagir le polymère d’ester de 1,2:5,6-dioxyisopropylidène-D-glucofuranose avec un acide faible pour obtenir un ester de polyglucose, et à soumettre l'ester de polyglucose à une réaction de greffage avec un nanotube de carbone pour obtenir le nanotube de carbone modifié. De par l’utilisation d’un polymère contenant un groupe glucose pour modifier un nanotube de carbone, le procédé de préparation du nanotube de carbone modifié peut être appliqué à la préparation d’un réactif permettant de détecter une cellule cancéreuse.
