Abstract

The effects of plasma surface modification on interfacial behaviors in carbon nanotube (CNT) reinforced alumina (Al2 O3) nanocomposites were studied. A unique plasma polymerization method was used to modify the surfaces of CNTs and Al2 O3 nanoparticles. The CNT- Al2 O3 nanocomposites were processed by both ambient pressure and hot-press sintering. The electron microscopy results showed ultrathin polymer coating on the surfaces of CNTs and Al2 O3 nanoparticles. A distinctive stress-strain curve difference related to the structural interfaces and plasma coating was observed from the nanocomposites. The mechanical performance and thermal stability of CNT- Al2 O3 nanocomposites were found to be significantly enhanced by the plasma-polymerized coating.
