The stable thermal conductivity was measured as a function of temperature. A number of techniques, such as FTIR, FESEM and UV-vis spectrophotometer were employed to characterise both dispersion stability and morphology of functionalised materials. By using ultrasonic test time, the highest stability of nanofluids was achieved at 60 minutes. As a result, the thermal conductivity displayed by CF-MWCNTs was higher than distilled water. In conclusion, improvement in thermal conductivity and stability displayed by CF-MWCNTs was higher, while the best thermal conductivity improvement was recorded at 31. © 2020 Published under licence by IOP Publishing Ltd. publisher: Institute of Physics Publishing date: 2020 type: Conference or Workshop Item type: PeerReviewed identifier: Hussein, O.A. and Habib, K. and Nasif, M. and Saidur, R. and Muhsan, A.S.
