Intelligent energy dissipation capability of CNTs based nanofluid

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A nanofluid with effective energy dissipation capability is developed with functionalized carbon nanotubes (CNTs) and nonwetting high surface tension liquid. Both CF4 plasma treating and fluorosilane grafting methods were performed to modify the properties of tube inner walls. By adjusting the plasma treating pressure, time and the chain length of the grafted fluorosilane, the functionalized CNTs based nanofluids could achieve different energy dissipation capabilities. From the XPS, TGA and TEM test results, it is found that the tube inner surface treating rate mainly determines this energy dissipation capability. Among the functionalized CNTs, the CF4 plasma treated SWCNTs achieve the highest dissipation capability, which is mainly due to the small pore diameter and high inner surface treating rate.
