Zusammenfassung:	This article presents the study of melt compounding of polystyrene (PS) with various types of titanium dioxide (TiO2) nanoparticles and surfactants, using a corotating twin screw extruder with multiple screw element configurations. It was found that a properly designed high shear screw configuration and the copolymer of silicone, ethylene oxide, and propylene oxide‐based surfactant produced the greatest degree of nanoparticle dispersion in PS/TiO2 nanocomposites, whereas a silane‐based surfactant and silicon dioxide (SiO2) or aluminum oxide (Al2O3) coated TiO2 nanoparticles yielded nanocomposites with the least photocatalytic degradation effects and the best retention of tensile and impact properties.
