Abstract

High-density poly(α-methylene-γ-butyrolactone) (PMBL) brushes were produced by surface-initiated atom transfer radical polymerization of α-methylene-γ-butyrolactone (MBL), a biomass derived from tulips, on a silicon substrate. The relative elastic modulus was evaluated through force-curve measurements using a scanning force microscopy. The friction coefficient was measured using a macroscopic friction test. The PMBL brushes exhibit larger elastic modulus and better friction resistance than PMMA brushes as a result of the highly stretched conformation and polar interaction between PMBL chains.
