▎ 摘 要
Hydrogenated carbon films with embedded multilayer graphene were prepared by magnetron sputtering a Ni target in methane. The films demonstrate ultra-elastic recovery (81%) and low friction coefficient (0.06), in contrast with films that did not contain graphene, whose elastic recovery and friction coefficient are 50% and 0.12, respectively. The excellent mechanical properties were attributed to the presence of multilayer-graphene embedded in amorphous carbon matrix. (C) 2012 Elsevier B.V. All rights reserved.
