Low‐Surface‐Free‐Energy Materials Based on Polybenzoxazines

Abstract

How low can you go? Polybenzoxazines can display surface free energies which are even lower than that of pure poly(tetrafluoroethylene). The contact angles and surface free energies were monitored during the polymerizations (see graph for an example). These materials are cheaper to prepare and easier to process than fluoropolymers.
