  • METHOD FOR NANOMORPHOLOGICAL MODIFICATION OF POLYETHER ETHER KETONE SURFACE BY HOT PRESSING, MODIFIED POLYETHER ETHER KETONE MATERIAL AND APPLICATION THEREOF
    Publication number: 20240270904
    Abstract: Disclosed is a method for nanomorphological modification of polyether ether ketone (PEEK) surface by hot pressing, relating to the technical field of biomaterials. The method includes the following steps: S1, preparing SiO2 nanospheres; S2, uniformly laying the SiO2 nanospheres prepared in the S1 on a surface of a PEEK material; S3, heating the surface of the PEEK material to a temperature higher than a glass phase transition temperature, then carrying out hot pressing to embed the SiO2 nanospheres into the surface of the PEEK material, and naturally cooling at room temperature after the hot pressing; S4, after cooling, using NaOH solution to corrode and remove the SiO2 nanospheres on the surface of the PEEK material after hot pressing in S3 to form a structure with nanoconcaves, then obtaining a hot-pressed modified PEEK material.
