Abstract

The invention relates to the technical field of surface modification of biomedical polymer materials, and in particular, relates to a method for preparing a multi-scale porous structure on the surface of polyether-ether-ketone, wherein the method comprises the steps: putting polyether-ether-ketone in an ultrasonic field, carrying out sulfonation treatment, and forming the multi-scale porous structure on the surface of polyether-ether-ketone. 100-2000 nm small-scale holes are generated through sulfonation, and cell behaviors can be regulated and controlled; and large-scale holes (50-250 [mu]m) generated by ultrasonic cavitation allow tissue and blood vessels to grow in, and the combination of the small-scale holes and the large-scale holes allows the tissue and the blood vessels to grow in and also can regulate and control cell behaviors.

Description

technical field [0001] The 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 intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Polyetheretherketone (PEEK), as a biomedical polymer material that can "substitute metal", has been widely used in hard tissue repair fields such as spinal fusion, skull repair, and artificial hip joints in recent years. PEEK has good biocompatibility. Thanks to its excellent chemical stability, it will not produce any harmful chemical substances when implanted in the body. The mechanical ...
