Superlubricity has attracted overwhelming attention due to the ability to provide negligible friction between sliding solid surfaces. In article 1600531 by Yuhong Liu, Jianbin Luo, and co‐workers, ultralow friction coefficient (μ < 0.01) can be easily obtained by a polyalkylene glycol (PAG) aqueous solution. During the sliding process, a hydrated layer is formed by hydrogen‐bonded PAG chains to lower the shear strength between two solid surfaces. Meanwhile, the mixed free water molecules effectively weaken interactions among entangled polymer chains. This finding has a significant potential in industrial applications.
