Hydrogen Passivation Induced Dispersion of Multi-Walled Carbon Nanotubes

A method combining hydrogen passivation and ultrasonication was developed for the first time to disperse multi‐walled carbon nanotubes (MWCNTs) in ethanol solution and epoxy resin. Excellent dispersion of MWCNTs was achieved in both media. Three‐point bending tests of the MWCNT/epoxy nanocomposites...

Zusammenfassung:	A method combining hydrogen passivation and ultrasonication was developed for the first time to disperse multi‐walled carbon nanotubes (MWCNTs) in ethanol solution and epoxy resin. Excellent dispersion of MWCNTs was achieved in both media. Three‐point bending tests of the MWCNT/epoxy nanocomposites revealed a remarkable increase in elastic modulus with increasing MWCNT content.
