- Abstract
- The present study aimed to evaluate simple, efficient approach to improve dispersion and electrical conductivity of nanofluid. In this study, chemical treatment and dispersion technique used to develop the dispersion and electrical conductivity of MWCNTs in aqueous. The surface of MWCNTs was modified by chemical oxidation with potassium persulfate/sodium hydroxide (K2S2O8/NaOH) to achieve more hydrophilic MWCNTs. NC (Nano Cellulose) used as the dispersion for nanofluid. As a result, dispersion characteristics examined by UV-Visible spectrophotometer revealed that best dispersion of MWCNTs obtained for chemically modified MWCNTs with K2S2O8/NaOH. From the electrical conductivity measurement, chemically treated MWCNTs with dispersant showed highest conductivity 210μS/cm. With the overall results, chemical treatment and dispersion method can play significant role in improving the dispersion and electrical conductivity of MWCNTs nanofluids. ? 2019 Trans Tech Publications, Switzerland
