摘要：
In this work, monomer casting nylon-6 (MCPA6)/melamine foam (Me)/graphene oxide (GO)/paraffin wax (PW) composites were synthesized using Me foam as a three-dimensional template and adsorbing GO and PW on the Me foam skeleton. The microstructure and tribological behaviors of the MCPA6/Me/GO/PW composites were determined and the interaction of PW with GO were theoretical investigated. The results showed that the addition of both GO and PW significantly improved the tribological properties of the composites. Compared with pure MCPA6, the friction coefficient and specific wear rate of the composite with the ratio of 2:3.5 (GO to PW) were reduced by 82% and 84%, respectively. The improvement of tribological performance was attributed to the synergistic lubrication and anti-wear effects of PW and GO.
