We examined the polar anchoring coefficient (Aθ) of nematic liquid crystal (NLC) on poly(hexyl methacrylate) (PHMA) brushes by the Freedericksz transition method. On PHMA brushes with 40 nm in thickness and at a density (σ) of 0.4 chains/nm2, the NLC exhibited an Aθ value of 2.2 × 10-5 J/m2, which is 1/40 as much as polyimide (PI). The Aθ increased with increasing the σ up to 0.1 chains/nm2 and then approached 1 × 10-5 J/m2 with further increasing σ to 0.7 chains/nm2.
