NOVELTY - Method of using two-dimensional filler for promoting orientation of one-dimensional fillers in cell walls of foamed material comprises (i) melt-blending one-dimensional (1D) nano filler and the two-dimensional (2D) nanometer filler with the polymer matrix material, and preparing the resulting blend into a molded green body, where in the molded body, the total amount of 1D nanofillers and 2D nanofillers accounts for 5-10 wt.% of the polymer matrix material, and (ii) foaming molded body by high-pressure fluid, and during the cell growth process, subjecting cell walls to two-dimensional stretching, subjecting 1D nanofillers around the 2D nanofillers to nano-confined shear, and promoting the in-plane orientation of 1D nanofillers in the cell walls. USE - The method is useful for two-dimensional filler for promoting orientation of one-dimensional fillers in cell walls of foamed material, which is useful in intelligent sensing material, electromagnetic shielding material, dielectric energy storage material, heat conducting material and anti-aging material. ADVANTAGE - The method: improves conductive performance of the composite foaming material prepared by foaming, electromagnetic shielding performance or dielectric performance; enhances the interfacial polarization effect of the nano-filler and conductive communication network structure.
