Superplastic Behavior of Alumina Composites Mediated by Carbon Nanotubes

The high temperature creep behavior of carbon nanotube(CNT)/alumina was mediated by the surface chemical functionalization used for synthesis of composite powders. Non-covalent functionalized carbon nanotubes make composites ductile, but covalent approach leads composites that are creep-resistant. O...

Beschreibung
Zusammenfassung:	The high temperature creep behavior of carbon nanotube(CNT)/alumina was mediated by the surface chemical functionalization used for synthesis of composite powders. Non-covalent functionalized carbon nanotubes make composites ductile, but covalent approach leads composites that are creep-resistant. Oxygen vacancy mechanism is proposed to account for this mediation effect in this communication.
