Abstract

An effect of surface segregation of polyhedral oligomeric silsesquioxanes (POSS) on surface physical properties was investigated. Hard coating layer with various MA₈POSS loadings was prepared on a bilayer of soft layer and PMMA substrate via a UV curing process. The scratch resistance of the coating layer showed specific properties. When MA₈POSS loadings in the coating layers were less than 10 wt %, the coating layers showed a great performance in scratch resistance. While MA₈POSS loadings were higher than 10 wt %, the surface performance was deteriorated. This is because the outermost surface of the coating layer was covered by MA₈POSS molecules when the MA₈POSS loadings were higher than 10 wt %, resulting in uncompleted curing reaction caused by large steric hindrance of MA₈POSS.
