A kind of hydrophilic nano-SiO2 was applied to poly(ethylene terephthalate)/polyamide-6 (PA-6) blends. Melt-blended composites were prepared at various component ratios and different nano-SiO2 levels. Mechanical, morphological, dynamic mechanical, and thermal tests were carried out to characterize the properties, morphology, and compatibilization of the composites. Increased impact strength, tensile strength, and modulus were observed by adding nano-SiO2 particles in the blends. The nano-SiO2 particles were found to be preferentially dispersed in PA-6, resulting in an increase of glass transition temperature and crystallization of PA-6. The mechanism of morphology and properties changes was discussed based on the selective dispersion of nano-SiO2 particles in the blends. © 2007 Wiley Periodicals, Inc.
