Abstract

Surface functionalization of multi-walled carbon nanotubes(MWCNTs) by opioid antagonist drug of Naltrexone via chemical modification of carboxyl groups,using of reagents di cyclohexyl carbodiimide(DCC),1-ethyl-3[3-dimethylaminopropyl] carbodiimide hydrochloride(EDC),N-hydroxysuccinimide(NHS),1-hydroxybenzotriazolemonohydrate(HOBT),O-(Benzotriazole-1-yl)-1,1,3,3-tetramethyluraniumtetrafluoroborate(TBTU),were performed. In synthetic organic chemistry,compounds containing the carbodiimide functionality are dehydration agents and are often used to activate carboxylic acids towards amide or ester formation. Carboxylic acids will react with the carbodiimide to produce the key intermediate as O-acylisourea which can be considered as a carboxylic ester with an activated leaving group.We have used of five carbodiimide reagent to synthesis twelve sample in this work.The resulting materials were characterized by different techniques,such as Fourier transform infraredspectroscopy (FT-IR), Thermogravimetricanalysis (TGA),Raman spectroscopy,Scanning Electron Microscopy (SEM),Field Emission Scanning Electron Microscopy(FESEM),Atomic Force Microscopy(AFM),High performance liquid chromatography(HPLC).
