▎ 摘　　要

A two-dimensional (2D) heterogeneous coupling nanoparticle composed of graphene oxide and zirconium phosphonate (GO-ZrP) was synthesized layer by layer in a self-assembly manner. A rigid layer of zirconium phosphonate can inhibit the curling of graphene oxide and then improve its dispersion. The GO-ZrP was then applied to phenolic resin-based friction materials by blending and hot pressing to improve their friction properties. The results show that the phenolic resin-based friction materials modified by GO-ZrP possess excellent tribological, mechanical, and thermal properties. Also, the specific wear rate of the material decreased nearly fivefold with the optimal loading, while the friction coefficient was basically stable. Synergistic effects between GO and ZrP nanosheets provide good prospects for the application of 2D nanofillers in friction materials. (c) 2018 Wiley Periodicals, Inc. J. Appl. Polym.
