Abstract: Provided are a polyaryl-based nanocomposite which shows excellent heat resistance and transparency even with using no compatibilizer and is useful for an LCD substrate or a plastic display substrate employing an organic EL, and its preparation method. The polyaryl-based nanocomposite is prepared by dispersing an aluminosilicate-based layered inorganic material in a polar solvent, and mixing it with a polysulfone-based polymer solution with stirring, wherein aluminosilicate-based layered inorganic material is a layered inorganic material modified with a polysulfone-based polymer having an onium group represented by the formula 2. In the formula 2, n is an integer of 1-100; R is a primary amine group, a secondary amine group, a tertiary amine group or an aromatic amine group; and Ar is -Ph-C(CH3)2-Ph- or -Ph-SO2-Ph-.
