Abstract
A method for preparing a composite material, including the following steps: providing metal oxide nanoparticles and a polyaromatic compound having a structure represented by Formula I, where, Ar, Ar, Ar, and Arare selected from aromatic rings; X, X, and Xare selected from active groups configured for binding with the metal oxide nanoparticles, each of R, R, and Rindependently contains at least one of alkylene, amine, —N═N—, alkenyl, alkynyl, and phenyl, and each of m, n, and y is independently selected from 0 or positive integers; dispersing the polyaromatic compound and the metal oxide nanoparticles in a solvent to yield a mixed solution; and heating the mixed solution to yield the composite material. A composite material includes: a polyaromatic compound and metal oxide nanoparticles. The polyaromatic compound is connected to the metal oxide nanoparticles. The polyaromatic compound has a structure represented by Formula I.
