We report on the preparation of polydimethylsiloxane (PDMS) coated multi-walled carbon nanotubes (MWNTs) followed by their dispersion in various solvents. To disperse MWNTs without acids of surfactants, which are the commonly used methods, hydrophobic PDMS coating was selected. It was determined that the PDMS coated MWNTs are more dispersed in diverse solvents such as dimethyl formamide (DMF) and acetone than bare MWNTs. In case of DMF solvent, dispersion of MWNT was improved by 40 % upon PDMS-coating of MWNT, which was confirmed by UV/Vis absorption spectroscopy. In this work, the PDMS coated MWNTs dispersed solution was also used for the fabrication of film, which is conductive, transparent and superhydrophobic because of the reduced aggregation and increased water repellency of MWNTs.
