| titleOfInvention | A kind of preparation method of polySchiff base cerium salt hybrid graphene composite foam absorbing material containing quinone structure |
| abstract | The invention discloses a preparation method of a quinone structure-containing polySchiff base cerium salt hybrid graphene composite foam wave absorbing material. The composite foam is composed of a quinone structure-containing polySchiff base cerium salt and reduced graphene oxide. Among them, the polySchiff base cerium salt has a long-chain conjugated structure, and the rare earth metal cerium ion with less than 4f orbital electrons can coordinate with the Schiff base to form a large conjugated structure, which widens the electron transport space and is conducive to dielectric polarization. and electromagnetic wave losses. The preparation steps are as follows: (a) ultrasonically dispersing the ball-milled polySchiff base cerium salt and graphene oxide dispersion liquid under the action of a surfactant; (b) adding an appropriate amount of ethylenediamine and stirring evenly, and sealing the reaction to obtain a hydrogel. (c) freeze-drying to obtain a polySchiff base cerium salt graphene composite foam absorbing material containing a quinone structure. The preparation method of the invention is simple, the obtained composite foam is light in weight, and has good wave-absorbing performance, and has practical value in applications such as preventing electromagnetic wave radiation interference or eliminating electromagnetic wave pollution. |
