Back ground: PEEK has been presented as a potential replacement for metal, zirconia, and glass ceramics. It is a thermoplastic partly crystalline high-performance polymer (HPP) made of an aromatic benzene molecular chain joined by functional groups from ether and ketone. Objectives: To use a scanning electron microscope (SEM) examination to determine how various acids affect the surface topography of PEEK material.
