Metal nanoparticle loaded graphene aerogel high-elastic composite material and preparation method thereof
The invention relates to the technical field of graphene, in particular to a metal nanoparticle loaded graphene aerogel high-elastic composite material and a manufacturing method thereof.The composite material is composed of, by mass, 10-20% of reduced graphene oxide aerogel and 10-20% of metal nanoparticles. The rest is reduced graphene oxide aerogel; the composite material takes a graphene oxide dispersion liquid and metal chloride powder as raw materials, and is prepared by the following steps: forming and preparing graphene oxide aerogel, soaking in a transition metal salt solution, reducing by a wet chemical method, and freeze-drying. The graphene aerogel high-elastic composite material obtained by the invention is controllable in structure, low in density, good in mechanical compression performance and high in rebound resilience, simple and convenient in preparation and forming process, high in controllability, low in cost and suitable for large-scale production.
