The invention discloses a preparation method of surface-functionalized modified CF/PPS composite material, relating to the technical field of composite materials. The technical scheme is as follows: polyphenylene sulfide resin, polyaniline-graphene functionalized surface-modified carbon fiber and processing additives are respectively fed into a twin-screw extruder from the main feeding port, side feeding port and main feeding port, and melt-blended, extruded, stranded, cooled, pelletized and dried via the twin-screw extruder to obtain the surface-functionalized modified CF/PPS composite material. The invention provides a phase interface modification scheme that neither damages the carbon fiber surface nor moderately increases phase interface bonding force and strength. The prepared surface-functionalized modified CF/PPS composite material has excellent mechanical and thermal properties as well as high electrical conductivity, meeting the comprehensive requirements of rapidly developing modern fields for high-performance materials.
