AI Technical Summary

Technical Problem

The adhesion of the metallized coating on the surface of existing PEEK materials is weak, and it is easy to peel off, especially in extreme environments, which affects the electromagnetic shielding effect and communication signal transmission.

Method used

Cu+ and Ni+ ions are generated in PEEK material by laser-induced generation of Cu-Ni coordination compounds, and embedded into the PEEK substrate through electroplating to form an embedded conductive layer. Combined with low dielectric filler and antioxidant, the coating adhesion is improved and the material properties are maintained.

Benefits of technology

It significantly improves the adhesion of metal coatings, maintains the lightweight and high performance of materials, reduces signal transmission loss, and ensures stability and electromagnetic shielding effect in extreme environments.

Abstract

The invention provides a laser-induced surface metallized glass fiber reinforced polyether-ether-ketone modified material and a preparation method thereof. The laser-induced surface metallized glass fiber reinforced polyether-ether-ketone modified material is prepared from the following components in percentage by weight: 39%-69.5% of PEEK resin, 20%-40% of low-dielectric flat glass fiber, 5%-10% of low-dielectric filler, 5%-10% of Cu-Ni coordination compound and 0.5%-1% of antioxidant. According to the invention, the Cu-Ni coordination compound is added into the PEEK modified material, then the PEEK modified material is subjected to laser induction treatment with a specific wave band, reducing cuprous ions or nickel ions are obtained on the surface layer of the PEEK modified material, and then the reducing cuprous ions or nickel ions are catalytically reduced into metal atoms through an electroplating process, so that the metal layer is embedded into the PEEK base material, and the binding force between the metal coating and the PEEK base material is improved.
