Polyether ether ketone (PEEK) is a high polymer composed of a repeating unit containing one ketone bond and two ether bonds in the main chain structure, which is a special polymer material. It has physical and chemical properties such as high temperature resistance and chemical corrosion resistance. It is a semi crystalline polymer material, which can be used as high temperature resistant structural material and electrical insulation material, and can be compounded with glass fiber or carbon fiber to prepare reinforcement materials. Generally, a class of polyarylene ether polymers obtained by condensation with aromatic binary phenols are used. This kind of material has been widely used in aerospace field, medical equipment field (as artificial bone to repair bone defects) and industrial field.
