Polymer materials are widely used for space structures such as satellite members, thermal blankets, adhesives, lubricants etc. There are many hazards for polymers in space environment such as atomic oxygen, UV radiation, ionizing radiation, high vacuum etc. In particular, AO is the most damage source in the low earth orbit (LEO). This paper provides a method of modifying the surface of PEEK sheets by direct-fluorination to protect them from AO. Chemical analyses and tensile test were carried out to study material properties of fluorinated PEEK. AO irradiation experiments were conducted to investigate AO resistance properties of fluorinated PEEK. The results showed that the fluorinated PEEK had better tensile properties than the pristine PEEK, and that AO erosion resistance of PEEK was improved by direct-fluorination method.
