Study Of Supramolecular Made By Cyclodextrin And Carbon Nano-Materials And Of Its Properties

The construction of supramolecular system and the modification ofCarbon nano-materials have attracted much attention on material fild.Muti-Walled Carbon Nanotubes and graphene have become an importantdirection in the supramolecular research due to their unique chemical andphysical properties. This paper is proposed to construct and investigate asupramolecular system prepared by modified Muti-Walled CarbonNanotubes and modified graphene with cyclodextrins.The main contents are illustrated as follow:Muti-Walled Carbon Nanotubes were acidied, and then esterificatedwith polycaprolacton, forming organic-inorganic hybrid material, whichcan be solved in organic solvent such as chloroform，methylene chloride.And the as-prepared organic-inorganic hybrid material was transformedinto inclusion complex with a construct of pseudopolyrotaxane. Theas-prepared material which was identified by DSC, FTIR had potentialapplications in biology and drug-chemistry fields.The graphite was oxided by Hummer’s method to yield grapheneoxide whose morphology, dispersion state and degree of oxidation were investigated. Then graphene oxide was modified by β-cyclodextrins,yielding GO-CD. After that, the organic-inorganic supramolecular hybridwith a net work structure was prepared by GO-CD and naphthalene endedepolyethylene glycol, whose structure was identified by LPSA,1H NMR andso on. Such material has potential applications in biology anddrug-chemistry fields.Polyethylene glycol monomethyl ether was induced onto the edge ofgraphene oxide by esterification, and included by α-cyclodextrins, forminggraphene hybrid with Pseudopolyrotaxane Structure. the structure wasidentified by DSC and FTIR. Meanwihle, the graphene hybrid can betransformed into supramolecular hybrid hydrogel with thermo-responsiveproperty. The supramolecular hybrid hydrogel can be transformed intosolution when the temperature accelerates, while re-transformed intohydrogel when the temperature drops. Such material has potentialapplications in biology and drug-chemistry fields.The researches disclosed above have introduced the supramolucrlarinteraction into the field of organic-inorganic materials, which havepotential applications in the fields of drug delivering and tissualengineering.
