Abstract
The invention provides a polyetheretherketone (PEEK) composite and a method of preparing same. The PEEK composite is prepared from 55-90 parts by mass of PEEK, 5-30 parts by mass zinc aluminum (ZA) alloy, 5-15 parts by mass graphite, 0.3-1 parts by mass graphene oxide (GO) and a processing additive. The PEEK composite is prepared by the following steps: putting the ZA alloy into an aqueous solution of a quaternary ammonium salt surfactant, ultrasonically dispersing, filtering, washing and drying; dissolving the GO in deionized water, dispersing the ZA alloy in deionized water, and adding a GO solution dropwise to a ZA alloy dispersion to obtain a GO/ZA alloy complex; mixing the PEEK, the GO/ZA alloy complex, the graphite and the processing additive, and drying at 100-120° C. for 3-4 h; and mixing in a mixer, and carrying out compression molding at 380-400° C.
