titleOfInvention | A method for preparing multi-scale porous structures on the surface of polyetheretherketone |
abstract | The present disclosure relates to the technical field of surface modification of biomedical polymer materials, in particular to a method for preparing a multi-scale porous structure on the surface of polyetheretherketone, comprising: placing polyetheretherketone in an ultrasonic field for sulfonation treatment, The polyetheretherketone surface forms a multi-scale porous structure. Sulfonation produces small-scale pores of 100-2000 nm, which can regulate cell behavior; ultrasonic cavitation produces large-scale pores (50-250 μm), which allow tissue and blood vessel ingrowth. Cell behavior is regulated. |
