▎ 摘 要
NOVELTY - Preparation of graphene/ferrite-based passive frequency-controlled material comprises preparing graphene solution by redox process; preparing hexagonal nickel-zinc ferrite using chemical coprecipitation method; mixing graphene solution, gamma -glycidyloxypropyltrimethoxysilane and organic solvent, ultrasonic dispersing, vacuum-drying to obtain graphene functionalized modification; mixing graphene functionalized modification, nickel-zinc ferrite and ball milling auxiliary agent, stirring, ball milling, cooling, filtering to obtain precipitate and vacuum-drying to obtain powder; and mixing powder, fluorine rubber and auxiliary agent to obtain mixed rubber and vulcanizing to obtain material. USE - Method for preparing graphene/ferrite-based passive frequency-controlled material. ADVANTAGE - The material transmits electromagnetic waves in working frequency band of radar antenna, absorbs electromagnetic waves in frequency band needing stealth, realizes stealth of missile or fighter seeker or communication window and has important military value and strategic significance.
