At present, the main modification methods of PEEK materials include fiber reinforced PEEK, inorganic filler filled PEEK, Anti Static Sheet ,and organic material blending modification.
1. Fiber reinforcement
Glass fiber, carbon fiber and various whiskers have good affinity with polyetheretherketone, so they are often selected as filler-reinforced polyetheretherketone to make high-performance composite materials and improve the strength of polyetheretherketone resin. , use temperature, etc.
2. Inorganic filler filling modification
The inorganic fillers that can be used for filling are usually micron and nanoscale inorganic particles. Nanoparticles not only have the properties of size effect and high chemical reactivity, but also can interact with the polymer interface.
3. Organic blending modification
Blending polyetheretherketone with organic polymer materials with higher glass transition temperature can not only improve the thermal properties of composites and reduce production costs, but also have a great impact on their mechanical properties. PEEK can be blended with polymers PTFE, LCP, PEI, PI, etc.
