Abstract: A resin nanocomposite, including a resin skeleton structure and nanoparticles. The resin skeleton structure is an aminated polystyrene. The nanoparticles are dispersed in the resin skeleton structure. The specific area of the nanocomposite is between 50 and 300 m2/g, and the pore size thereof is between 5 and 40 nm. The invention also provides a method for preparing the resin nanocomposite, the method including: 1) mixing and dissolving a linear polyethylene with a chloromethyl polystyrene or a polyvinyl chloride to yield a polymer solution, and adding the nanoparticles to the polymer solution; 2) adding an alcohol solution to liquid nitrogen; adding the mixed solution dropwise to the liquid nitrogen to yield a mixture; allowing the mixture to stand; collecting, washing and drying resin beads to yield a composite material; and 3) adding the composite material to an amine solution for reaction, and washing and drying the resulting product.
