Bio-based plastics can be designed with superior hardness and thermal properties comparable to conventional petroleum-based plastics. However, bio-based plastics often meet the processing challenges, and the brittleness limits the industrial application. A high density poly(α-methylene-γ-butyrolactone) (PMBL) brush film was prepared, and the molecular aggregation structure and tribological properties were studied. The PMBL and poly(methyl methacrylate) (PMMA) brushes exhibited a thickness larger than random coil dimension but lower than extended-chain conformation, indicating that a densely packed brush layer was formed and the chain conformation has been stretched almost perpendicular to the substrate. The PMBL brushes exhibited stable friction coefficient of ∼ 0.2 after 400 friction cycles, demonstrating a better wear resistance. Although the slight wear track was formed on the brush surface during the friction test, a decreased amount of wear debris and an overall smoother wear track were observed. This suggests that the PMBL brushes have a potential for practical scratch resistant applications. This is an abstract of a paper presented at the 2013 STLE Annual Meeting & Exhibition (Detroit, MI 5/5-9/2013).
