The Influence Surface Modification of CNT Using Surfactant to Formation of Composite

The nature of pure CNT has a hydrophobic surface and low dispersion stability. To increase CNT dispersibility, it is necessary to modify the CNT. One possible way to modify the electronic and vibronic properties of CNT is charge and functional transfer. Addition of surfactant to CNT is to increase the solubility of CNT in water which produces functional groups from the surface of nanotubes with anionic and cationic groups. The purpose of this study was to study the effect of surfactant addition on CNT treatment on CNT properties. Pure CNT samples that have been added to the surfactant are sonicated for 1 hour then dried. From the results of X-ray Dispersive energy characterization (EDX), there is an increase in the amount of oxygen in the CNT after the addition of surfactant compared to pure CNT. From the results of Fourier Infrared Transformation (FTIR) shows that the process of adding surfactants will produce functional groups on the surface of the CNT. The SEM characterization showed no morphological changes in CNT, this was also stated by the results of X-ray Diffraction (XRD).
