Synthesis and Properties of Perfluorocyclobutyl Aryl Ether-Based Hydrophobic Polycarbonate

A novel hydrophobic polycarbonate containing perfluorocyclobutyl (PFCB) aryl ether was synthesized from commercially available p-methoxyphenol.The polymer exhibited excellent thermal stability and hydrophobicity without reducing the transparency of the material.The thermal decomposition temperature was 351 ℃ and the contact angle between the film and water was 110°.In order to further explore the effect of PFCB aryl ether structure on the properties of polycarbonate, a series of polycarbonates with different PFCB aryl ether group contents were synthesized from PFCB aryl ether monomer and bisphenol A monomer.By comparing their properties, the introduction of PFCB aryl ether structure into polycarbonate can reduce its dispersion and improve its thermal stability and hydrophobicity.
