Abstract

The multiwalled carbon nanotube (MWCNT) surface chemistry changes by microwave and UV/ozone treatments were studied and the treatment effects on the thermal conductivity of their polymer nanocomposites were investigated. Contact angle measurements, X-ray photoelectron spectroscopy (XPS) and Raman spectra were used for the CNT surface characterization. The surface functionalization and the CNT purification/annealing should be balanced for improving the thermal transport property of the MWCNT/polymer nanocomposites.
