▎ 摘 要
NOVELTY - Preparing graphene-loaded metal particles reinforced aluminum and aluminum alloy-based composite materials comprises e.g. (i) constructing graphene-loaded copper nanoparticles using sodium chloride as a template, where glucose is used as a carbon source and copper nitrate trihydrate as a copper source, dissolving sodium chloride, glucose and copper nitrate in deionized water, stirring uniformly, adding the mixed solution in a refrigerator for freezing to ensure that the sodium chloride crystal surface to form ultra-thin composite membrane coated with glucose-copper nitrate, using freeze drying technology to freeze-dry the solution to obtain the composite powder, and (ii) calcining the powder obtained in a high temperature under a hydrogen atmosphere, rapid cooling the temperature, calcining for a period of time, washing the calcined composite powder with deionized water, filtering and vacuum drying, and obtaining composite reinforced phase of graphene load copper nano-particles. USE - The method is useful for preparing graphene-loaded metal particles reinforced aluminum and aluminum alloy-based composite materials.
