The homogeneous polycarbonate/poly(acrylonitrile‐butadiene‐styrene) (PC/ABS) nanocomposite thin films were prepared by a facile solvent casting method using phenylene modified‐mesoporous silica materials as additives and dichloromethane as a solvent. The physicochemical analyses using small‐angle X‐ray scattering, nitrogen adsorption–desorption, solid‐state 13 C and 29 Si nuclear magnetic resonance, and scanning electron microscope were investigated to provide clear physical and chemical properties for modified‐mesoporous materials and nanocomposite films. Tensile tests were performed at room temperature according to ASTM D638. Rheological properties were also analyzed to observe any variance of solid–liquid property. As a compatibilizer and a reinforcing filler, mesoporous (organo‐)silicas showed enhanced features in rheological and mechanical properties. The sound absorption coefficient was measured by the impedance tube up to 6400 Hz according to ISO 10534‐2. It was found that the PC/ABS nanocomposites containing mesoporous materials can be used as a sound‐proofing support material depending on fabrication process. © 2017 Wiley Periodicals, Inc. J. Appl.
