Lamellar lyotropic liquid crystals were evaluated as lubricants in a slow sliding ball‐on‐disk friction rig. The liquid crystalline structure was modified by addition of a monomer and the influence of polymerisation on lubrication properties was studied. The results showed that partial polymerisation of a monomer located close to the polar group layer in the liquid crystal, followed by addition of a small amount of long‐chain aliphatic hydrocarbon, gives low friction coefficient and enhances load‐carrying capacity.
