Polybenzoxazines is well known to be advanced thermoset resin with many unique properties. More specially, the last decade has witnessed active research on polybenzoxazine based functional surface due to its ability of low surface free energy, which can be lower than the widely regarded low surface energy polymer, Teflon, without having fluorine atoms. Since polybenzoxazines are cheaper and easier to process compared to fluoropolymers, researches on polybenzoxazine-based functional surfaces have aroused attention in many fields of applications, such as anti-ice, anti-sticking, corrosion protection, liquid manipulation, oil/water separation, and self-cleaning, as shown in Fig. 1. In this talk, we will look at the advances in fabricating and investigating performance of functional surfaces based on polybenzoxazines and their composites, including effects of surface chemistry and surface chemistry on polybenzoxazines’ surface properties, molecule design and fabricating principals of the surfaces with controllable structure, wettability, adhesion, and other fascinating functionality. We analyze why and where the applicability of existing techniques falls short, and discuss several avenues for improvement, in order to provide guidelines for designing novel materials based on polybenzoxazines with desired properties.
