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.

Description

technical field

[0001] 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 polyether ether ketone. Background technique

[0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.

[0003] Polyetheretherketone (PEEK), as a biomedical polymer material that can "substitute metal", has been widely used in the field of hard tissue repair such as spinal cages, skull repair, and artificial hip joints in recent years. Polyetheretherketone has good biocompatibility, and thanks to its excellent chemical stability, it will not produce any harmful chemicals when implanted in th...
