摘　　要：Poor interfacial adhesion and dispersity severely obstruct the continued development of carbon nanotube(CNT)-reinforced epoxy(EP)for potential applications.Herein,hierarchical CNT nanohybrids using nickel phyllosilicate(Ni-PS)as surface decorations(CNT@Ni-PS)were synthesized,and the nanocomposites derived from varied mass fractions of EP and CNT@Ni-PS were prepared.The morphological structures,tribological performances,curing behaviors and thermal properties of EP/CNT@Ni-PS nanocomposites were carefully investigated.Results show that hierarchical CNT nanohybrids with homogeneous dispersion and well-bonded interfacial adhesion in the matrix are successfully obtained,presenting significantly improved thermal and tribological properties.Moreover,analysis on cure kinetics proves the excellent promotion of CNT@Ni-PS on the non-isothermal curing process,lowering the curing energy barrier steadily.
