Abstract In this work, surface modification technique with coupling agents and anchoring polymerization was adopted to tailor the surface properties of nanoscaled titanium dioxide (TiO<SUB>2</SUB>). Ethyl glycol sols with TiO<SUB>2</SUB> were prepared in order to simulate the dispersibility of differently modified TiO<SUB>2</SUB> in a molten polyamide 6 (PA6) matrix. The modified TiO<SUB>2</SUB> were melt compounded with PA6 and composites and fibers were prepared. The average filler diameter of 47 nm (in composites) and 44 nm (in fibers) indicated homogeneous dispersion of TiO<SUB>2</SUB> in the matrix, whereas unmodified TiO<SUB>2</SUB> showed agglomerated structures in the PA6 matrix. The mechanical properties of the composite fibers were improved as compared to pure PA6 fibers and composite fibers with unmodified TiO<SUB>2</SUB>.
