Patterned mixture component surfaces, offering a means for controlling the adhesion and the wetting behavior of materials, have attracted great interest. In this letter, a patterned dual-component lubricant film consisting of multiply-alkylated cyclopentanes (MACs) mobile lubricant trapped and maintained among the patterned octadecyltrichlorosilane self-assembled monolayer (OTS-SAM) network was fabricated on surfaces of silicon using an elastomeric stamp. Tribological behavior of the patterned MACs–OTS dual-component film was investigated, comparing with MAC film and patterned OTS-SAM. The patterned MACs–OTS dual-component film has shown to have improved load-bearing capacity, anti-wear, and self-lubricating ability. It can remain as an effective lubricant layer for more than 3,600 s as the load increased to 0.4 N, and the average friction coefficient is about 0.1. Compared with patterned OTS-SAM and MACs film, patterned MACs–OTS dual-component film showed best load-carrying capacity and durability at applied loads of 0.1–0.5 N.
