Surface Modification of Multi-Walled Carbon Nanotubes with Polysaccharides

Multi-walled carbon nanotubes (MWCNTs) are known as efficient drug carriers. To improve their interaction with other materials, surface modification of MWCNTs is necessary. In this work, were functionalized acid and polysaccharides (chitosan gelatin). The functionalization process was done via solutions nitric acid, sulfuric a mixture acid-sulfuric first, followed by chitosan gelatin. achieve the optimum condition functionalization, reaction time, temperature, ratio varied. Furthermore, effect gelatin addition into studied at various mass ratios. synthesized materials characterized Fourier transform infrared spectrophotometer, Boehm titration, dispersion test. titration results showed that functional groups had been attached successfully to surface. amount increased along time. highest acidic group obtained from data 2.33 mmol/g. It achieved when reacted for 24 hours. Temperature variations on did not provide significant results. From FTIR data, sharp peaks 3480 cm-1 1040 indicates -CONH bond, which shows have grafted onto an amide linkage. Moreover, test stable 48
