Abstract:
Polysilazanes are pre-ceramic polymers with a silicon-nitrogen backbone. In recent years they have developed as a high-performance binder in protective coatings for transportation vehicles, commercial and residential buildings, and industrial plants. Generally speaking, there are two classes of polysilazanes (Figure 1). One is inorganic perhydro-polysilazanes (PHPS) that feature H groups on both Si and N atoms, and the other one is organic polysilazanes (OPSZ) that have organic functional groups grafted onto Si atoms. They have emerged as a leading technology for durable surface protection.
Compared to siloxanes and fluoropolymers, polysilazanes offer outstanding heat stability, surface hardness, and hydrophobicity as well as comparable performance for corrosion and weather protection. This work reviews their structure-property relationship and highlights their advanced performance in high-temperature, surface hardness, weathering and corrosion protection, and anti-graffiti applications.
